Chiles Redux 

Reconstruction of the actual view of the object as seen from the DC-3 cabin
What is referred to as the Chiles-Whitted UFO encounter involved a night sighting from a DC-3 of a cigar-shaped object in 1948. This case has been considered one of the 'classic unknowns' of UFO history. However a detailed analysis of this sighting, taken together with other sightings the same evening, clearly show it was an earth-grazing fireball. It was not a nearby object traveling at 700 mph half a mile away and 500 feet above the Chiles' aircraft, but a disintegrating meteor, passing 80 miles away at 90,000 feet at a speed of 18 miles/second. If we go back to the Air Force Office of Special Investigations (AFOSI) original reports (available at the Project Blue Book Archive) and plot the bearings and altitudes of the objects sighted on that night, no other conclusion can be reached.

In 1948, earth-grazing fireballs were not recognized by science. The AFOSI investigators did not get the information in the terms later standard for scientific analysis. They asked the witnesses to estimate the distance, size, and speed of a luminous object sighted at night. This required the implicit assumption that it was the size of man-made objects and flying at speeds and altitudes contemporary aircraft might achieve. Later standard Blue Book forms would ask the observers to estimate the apparent size (compared to the moon), the elevation above the horizon, and the direction and duration of a sighting. This kind of information could then be analyzed to determine if it matched a small, slow, close object or a much faster, larger object farther away.

Based on the assumptions that the mundane speeds and distances reported were correct and the 'fact' repeated over and over that 'it couldn't be a meteor because meteors do not fly horizontally' AFOSI convinced themselves it was an extraterrestrial object.

The sightings of that evening were:

  • Eastern Air Lines pilot Feldvary, Trip 573, reported sighting an object from his DC-3, flying from Washington DC to Raleigh, North Carolina. It was some time after he had checked in with Blackstone control at 0219. He estimated the time at about 0230. The object was traveling about 20 deg over the western horizon, at a heading of around 230 deg (e.g. slightly west from his heading of 215 deg), and travelled through an arc of 80 degrees. Although no duration was given, it seemed to have 'terrific speed'.
  • Eastern Air Lines pilot Mansfield, Trip 571/23, reported sighting an object from his DC-3, flying from waypoint Blackstone to Greensboro, North Carolina. It was also some time after he checked in with Blackstone. He also estimated the time as 0230 (it may be he discussed the sighting with Feldvary and assumed the same time). The object was traveling 'in a horizontal direction, slightly above the horizon, at a heading of around 210 deg (e.g. slightly east from his heading of 240 deg). He did not report the arc of travel, but said it was only in sight for 3 seconds. This was probably a good estimate of the duration of the sighting, since the object "…was brighter than any I have seen before…" and he couldn't have avoided seeing it immediately as it began to flare in the large right side cockpit window of a DC-3.

At the time of these two sightings, Feldvary was flying about 60 miles east of Mansfield. So clearly the object had to be a considerable distance west of both aircraft to be low on the western horizon for both of them. If we average the two bearings reported, the object would have a bearing of 220 degrees, which is consistent with a bearing west of Feldvary and east of Mansfield.

  • Eastern Air Lines crew Chiles and Whitted, Trip 576, were en route from Houston to Atlanta, 25 miles southwest of Montgomery, Alabama, on a bearing of 50 deg when the famous sighting occurred. A strange object was sighted 'coming toward us at a high rate of speed'. It was flying straight and level, and created no noise or turbulence. It passed to the right side of the DC-3, at what they estimated as a distance of half a mile, a speed of 700 mph, at an altitude of 500 feet above their 5000 foot level. The object seemed to be 100 feet long, cigar shaped with rows of brilliantly illuminated portholes, with a stream of red fire trailing behind. What this translates to in objective terms was an object approaching at a bearing of 230 deg, at an elevation of 12 deg above the horizon, with an apparent size at closest approach of 3.4 deg (about seven times larger than the full moon). The object was only in view for at least 5 and not more than 10 seconds. Of course the close view in which details were seen would have been only for an instant as the object flashed by. The actual view from the cockpit at closest approach, as shown above, was rather mundane compared to the typical artists concepts of the encounter.
  • Air Force contract employee Massey sighted a cigar shaped object with a trail of flame from the aircraft ramp at Robins AFB, near Macon Georgia. Unfortunately he was not asked the elevation of what he saw above the horizon. He saw it first 'overhead'. This apparently meant in the sky to the west of his position, since although he stated he was facing north, he didn't see it come 'out of the north' and people normally watch things in their field of vision, not straight above them. It then traveled in a southwest direction, until disappearing in the distance. He estimated the object to be traveling straight and level at 700 mph, an altitude of 3000 feet, and having the 'size of a B-29'. He estimated the duration as 20 seconds and the time of the sighting as 0140 or 0150 based on the departure time of an aircraft he was preparing (this one-hour difference from the other sightings is not commented on by AFOSI, although they considered this the same sighting as Chiles). Massey was asked if the thought it was a meteor and said no, because 'a shooting star falls perpendicular. This object was on a straight and level plane'. Massey claimed to have seen V-1's in flight and even a V-2 launch in World War II, the latter 'during the Battle of the Bulge'. This was perhaps possible. V-2 Gruppe Sued operated within 50 miles of the front lines near the south Ardennes in November-December 1944 before being moved behind the Rhine.

Putting together in terms of the positions and bearings of the aircraft and the objects sighted, and the locations of the observers, the following consistent result is obtained:

Plotting of the four sightings show a consistent course for the object
Which is clearly the track of what science now knows as an Earth-grazing fireball. Such rare events were only accepted by science in 1972 when one was actually photographed and filmed as it flew over Utah.

AFOSI's assessment was that the first two sightings were of a different event - because the object was 'meteor-like', travelled at 'terrific speed', and flew 'parallel to the horizon', which was seen as different from the other two (which were reported as flying at 700 mph by 'trained observers'). They did not seem to notice that the bearing of the object sighted in the first two sightings was the same as that observed by Chiles and Massey, or that estimates of the size and distance of an object at night would be based on it being a conventional object, not something unknown to science or popular culture at the time.

The sighting was sensationalized by the press in books, including that ghost-written for one-time Project Blue Book commander Ruppelt. The sighting was later embellished, with the object coming 'within 700 feet', the aircraft being 'buffeted by turbulence', Chiles having to 'swerve to avoid collision'. None of which was in the original report…

In fact the original sighting report is rather mundane. The object was only in sight for perhaps only 5 seconds, was seen to be about seven times the size of a full moon (but only for a second at closest approach), appeared to be coming head on but then passed the aircraft to the right, at a closes approach estimated at half a mile, and caused no noise or turbulence. Based on this brief glimpse, Chiles and Whitted produced these sketches (considerably more informative than the later 'cleaned up' versions):



Today, after many movies about asteroid impacts, and especially the very real Chelyabinsk event, no other conclusion would have been reached by the observers or investigators but that this was a meteor. The cigar-shaped (dark, unseen) form was defined by the brilliant 'windows' on the object, which were undoubtedly the object disintegrating into glowing fragments as it passed through the atmosphere.

Heflin, Again



The Heflin UFO sighting and photographs are one of the classic UFO cases. Heflin was a highway maintenance engineer for California's Orange County. In 1965 he produced a series of four Polaroid photographs, showing a hat-shaped UFO travelling across a road just south of the Santa Ana Freeway, and the smoke ring left after its departure from the area. He estimated the object to be 30 feet in diameter and 700 feet away as it crossed the road in front of him. A new take on the photo analysis is provided below, which again concludes they are fakes. But completely obscured in the accounts to date were the extraordinary nature of a nearby military installation, its relationship to the location of the sighting, and the unusual interest by aerospace contractors in the photographs.

The Location

What was then known as Marine Corps Air Facility Santa Ana was located less than a mile southwest of the sighting location. The base originally began operations in 1942 as a US Navy lighter-than-air (LTA) vertical-takeoff-and landing (VTOL) airship base. Two immense hangars, Buildings 29 and 29, were built. Each hangar was 189 feet high, 1,088 feet long and 297 feet wide. They are registered as historical monuments and remain to this day among the largest wooden structures ever built. They can be seen for miles from the ground, tens of miles from any nearby elevation and from as far away as visibility will allow from the air. The Heflin investigators, although mentioning other minor local military facilities, make no mention of this remarkable site just a mile away.



From 1951 the base was used by the US Marine Corps for helicopter training and operations. The layout was suited for VTOL operations and the cavern-like hangars were used as helicopter maintenance shelters.



Although today being engulfed by industrial parks and shopping malls, in 1965 the area was still largely open fields, allowing helicopter training in preparation for the buildup in Vietnam. A Marine history noted:
LTA has always been considered the ‘pearl’ of Marine Corps bases. In addition to its perfect location among the Southern California orange groves and proximity to all of the Southern California amenities, it also provides a nearly perfect environment for training helicopter pilots...The nearby Saddleback mountains and adjacent foothills have 13 confined area mountain landing sites that every PUI (Pilot Under Instruction) has learned to hate and love.

So we have a facility that is already built for VTOL operations, with enormous hangars where an experimental VTOL craft could be tested far from prying eyes. Now if we superimpose the excellent sketch in the Condon report on a 1972 aerial photo of the base and the sighting location, we find that the Heflin craft was first sighted at a position exactly at the base runway bearing, but coming from Building 28 or one of the adjacent turning circles. Heflin reported the craft seemed to have stability problems. After it recovered, it accelerated away - at the same heading as the heading from the base, and towards the Saddleback mountain landing training area used by the Marines:
As the UFO traveled, it maintained a relatively level altitude (150 ft.) in relation to the flat terrain, however the UFO acted similar to a gyroscope when losing its stability. The UFO continued moving away slowly gaining altitude, tipped its top toward me slightly. It seemed to gain stability, then it increased its velocity (speed) and altitude more rapidly leaving a deposit of smoke-like vapor….The UFO disappeared in a northern direction toward Saddleback Mountain.


Unusual Interest

Now in the aftermath of the photographs becoming public, Heflin received some unusual contacts (aside from Marine Corps investigators, US Air Force investigators, Men in Black, NORAD, NICAP, Condon Report, and other UFO investigators!). The Condon Report notes:
Among numerous telephone calls, the witness says he received … one from … a man who identified himself as a representative of the Boeing Airplane Co. … The … man identified himself as an "engineer with the L.A. office of Boeing Aircraft… not representing Boeing, but personally interested, asked that his name not be mentioned or the fact that he had phoned. He also suggested that it might be better if [the witness] did not talk about the case …" Later "A letter came from a vice-president of McDonnell Aircraft, St. Louis, requesting technical information".
Forty years later, aerospace writer Nick Cook was interviewing Boyd Bushman, an engineer who was involved in heavily classified antigravity propulsion projects for Lockheed Martin. Cook noted, in his book The Hunt for Zero Point, page 254-255:
I spotted something among the collection of papers Bushman had given me. Tucked beneath the patents and company brochure material on weapons technology was a grainy photocopy of a UFO flying low over a straight stretch of desert road. A handwritten caption underneath identified the location as Santa Ana, California, and the date as 1966.
In 1965, according to his resume, Bushman was working as an engineer on the Redeye missile at General Dynamics at nearby Pomona, California.

This is all very interesting, but there is an obvious objection. Why would a heavily classified craft be tested in daylight from a Marine training base? One could theorize the craft was usually tested at night, but in this case went out of control in a daytime in-hangar test, and there was no choice but to let if fly out of the hangar on a course toward the usual landing test area?

Does the quick action of USAF investigators to discredit the photographs mean they were anxious to squelch the case to cover up the fact a classified craft had gotten loose? Can assertions by the Marines that nothing was tracked by radar be believed if this was the case? The Condon Report stated:
A check made by the Marine Corps investigators indicated that no UFO was observed on the Marine Corps Air Facility radar at the time of the reported UFO observation…the "Facility" referred to by the Air Force investigator is a relatively small base within direct sight of the Myford Road site, but contains only a sporadically used training radar installation. Marine officials interviewed 15 January 1968 were unable to determine whether radar was in service 3 August 1965.
One can wonder if it is fair to characterize a base with the some of the largest buildings in the world as a 'relatively small base'. Heflin himself noted the prevalence of Marine helicopter operations: "…the witness noted that nearby helicopters from the Marine Corps Air Facility could be heard, and that their noise could have drowned out sounds the UFO might have made…"

Even if the photographs were faked, we have an unusual interest from engineers in at least three aerospace companies in the event. Does this indicate there was industry scuttlebutt of some kind of a classified program with testing underway in Santa Ana…?

The Photographs

Conventional analysis has concentrated on the photographs. The official analyses concentrated on seeing if it was possible to fake the photographs, in which case they could be ignored as they proved nothing.

First up was US Air Force Foreign Technology Division "Photo Analysis Report 65-48" dated 14 August 1965. Controversially this report was dated one month before the photographs were made public. The Condon Report noted: "This raises the possibility, then, that without the knowledge of any of the principals, the Air Force was involved in the case less than two weeks after it happened… Officials of Project Blue Book informed the Colorado project in March 1968 that this question had been raised before, and that the Photo Analysis Report was in error, and that month should have read October".

Not mentioned but perhaps even more controversial was why FTD would be involved. At any rate, the report itself indicated that "…A test was conducted by the FTD Photo Analyst and Photo Processing personnel with the results shown on the attached photos… The object seen in the photographs was a 9" in diameter vaporizing tray, tossed in the air approximately 8 to 12 feet high at a distance from the camera of approximately 15 to 20 feet. The result of the test shows a surprising similarity between the object on the test photography and the object on photography."

The same figures appear in a Air Force release on 17 October 1965, except now they are characterized as coming from a careful analysis of the photo: "The camera was probably focused on a set distance and not on infinity as the terrain background was blurred… The center white stripe on the road and the object…have the same sharp image. Therefore it is believed that the object was on the same plane as the center white stripe (or closer) to the camera and could not possibly be the size quoted in the report. Using the width of the road as a factor, the size of the object was estimated to be approximately one to three feet in diameter and 15 to 20 feet above the ground." So it seemed that the rationale was 'backed into' based on a model test. In fact, examination of the photo does not show the background blurring the Air force statement alleged. Objects in the distance do fade into the haze, but they are not blurred.

The Condon Report did a different test: "In the course of my study I was able to simulate effectively the first three photographs by suspending a model [a camera lens cap] by a thread attached to a rod resting on the roof of a truck and photographing it. Without assuming the truth or untruth of the witness's story this has led me to conclude that the case is of little probative value…"

Both of these studies concluded that the photograph could be faked. However the methods and conclusions were different and contradictory. The Air Force used a thrown model 9" in diameter thrown 15 to 20 feet away, while the Condon investigator used a 3" lens cap suspended around 5 feet away. Normally a thrown object exhibits motion blur while a near object is out of focus if the background at infinity is in focus. However the Polaroid camera used had an uncommonly good depth of field and fast shutter speed (1/3000). It seems nothing in these analyses proved anything except that it was possible to make similar pictures using smaller nearby objects.

In 1967 researcher James McDonald believed the photographs represented a large, real object, except perhaps the last photograph of the smoke ring. McDonald became obsessed with studying how this photograph differed from the others, since if it was taken later at a different location in different weather, as he believed, it would undermine Heflin's credibility.

In 1975 an analysis concluded the photos were fake based on observation of a string supporting the object when the photos were enhanced. However this seems to have been an artifact in the particular copies of the photos analyzed. It does not appear in earlier or subsequent analyses of the original photos.

In 2000 a new digital analysis was conducted on the original Polaroid photos. This however emphasized enhancement by level equalization to bring out certain features on the base and exhaust from the object described by Heflin in his original description of the objects. No analysis was conducted on the distance of the object. A 'blur analysis' was promised for a second paper, still said to be forthcoming in 2006. However no such paper was ever produced, and in the meantime the originals have been withheld from research.

In 2005, a researcher noticed that the second and third Heflin photos could be considered as a single stereographic image since Heflin moved in the seat between the two images. Still some researchers didn't buy it or couldn't see it. Another look at this is provided below, which should convince skeptics.

By 2010 an acquaintance of Heflin named Edward Riddle reported that Heflin had told him that he had faked the photos using a model train wheel (Heflin was a known model train aficionado). Overlays of the photo with such wheels showed a good match.

A new examination by ufodna of the first photo considers the distance of the object according to the amount of haze. Items farther from a camera will generally have dimmer brights and lighter darks than those closer. A calibration is provided by the telephone poles, which are very dark indeed at the base; and the white stripe on the road median. Observing the darkest dark and lightest light at the distance of each pole provides a calibrated yardstick to measure the distance of other objects in the picture. The distance to the poles is known exactly thanks to the sketch of the site in the Condon report. The analysis proves the object is very close to the camera indeed:



An analysis of the parallax between the second and third pictures, similar to the 2005 3d image but showing the logic behind the conclusion, also proves without a doubt that the object was a small one, at the same distance from the camera as the rear view mirror:



The inevitable conclusion is the that Heflin photographs, as striking as they seem, and as sincere the photographer seemed, were fakes.

Now What?

So the photographs were evidently faked, but the sighting evoked extraordinary interest among aerospace contractors and many government agencies. Did Heflin accidentally initiate a hoax that seemed like a security breach to those who had a need to know about a government program?
