WESTALL, HIBAL & the balloon explanation
I posted the following contribution to the discussion:
Of course the HIBAL Westall hypothesis is a worthwhile exercise, however context, detail etc should inform the debate. While high altitude is required the balloon to be perhaps mistaken for a classic "flying saucer" (theres a good telescope picture of one at 40 km altitude in the 1976 NRC document "The Use of Balloons for physics & astronomy" - hardly would qualify for a close encounter!), at launch, low altitude, the balloon would be comparatively deflated. The size relationship of the payload and the balloon decreases with altitude. If the payload was in descent, to precipitate a "close encounter" then you would expect it would be attached to the deployed parachute. Continued attachment at low altitude would create a crash situation, I would suspect, hardly accounting for sighting observations over a small geographical area like Westall, that lend support to a UFO observation, let alone a close encounter at ground level, where the UFO takes off again. I would suspect if HIBAL was the culprit, it would have been blatantly obvious, and little need for a coverup. No one died, to the best of our knowledge, and the incident did not have catastrophic consequences at the state or national level. HIBAL was being summarised in the Australian government Year Books. It seems difficult to reconcile the sighting observations with HIBAL unless one disregards the many elements that seem more supportive of a UFO explanation.
Still HIBAL has utility as a possible explanatory data base for "UFO" sightings. I was looking at it as a possible explanation for the "UFO" seen in my "angel hair" experience, although I cannot for one moment see it explaining my ground level handling and apparent sublimation effects of the material in my hands. Anyway to this end I noted a HIBAL ASHCAN launch from Mildura on August 29, 1969, one day before my "angel hair" experience. The Kyogle area also had sightings on August 30, which some suggested was a high level balloon, but it was allegedly ruled out by some authorities. It now seems a likely explanation. Sadly NO DATA on landing point or if failure involved.
While the actual purpose of the balloon flights were often secret (eg. ASHCAN was nuclear air sampling), the balloon flights were not so much, other than deploying "weather balloon" as the standard response. In conclusion I would think a low level HIBAL "landing" or "hovering" etc would be readily obvious to most observers and the level of "coverup" reported seems totally disproportional to the possible sensitivities of the payload.
On balance I don't see HIBAL as being a good fit for Westall, but maybe for the "UFO" seen by others, not me, at Grafton and Kyogle on 30 August 1969. This doesn't explain my "angel hair" experience, with apparent sublimation observed, which seemed to me to take it out of the ballooning spider web category. That was the explanation I had as I paddled over to the "web fall", but that explanation evaporated quickly (pardon the pun) when I began handling the material.
My "retrieval team project" informant emailed me with the following info per this discussion: "I do not concur with Keith Basterfield’s working hypothesis in relation to Westall. "For what it’s worth, my own verbal enquiries made today into the matter have revealedAnyway I still think HIBAL has utility as a database for explaining some UFO events as suggested by my discussion of my 30 August 1969 experience. I didn't see the "UFO" in question, but my mother did, some other Grafton residents and a host of Kyogle resident also saw something, which may well have been a HIBAL balloon. It would have been an impressive sight. My mother described a sort of undulating shape which may well have been a good fit for a HIBAL balloon.
little : "DOS Hibal flight 292 was not launched from Mildura . 292 did not terminate in
Melbourne. "Series records were destroyed as stated. "I was not able to glean any other factual information. "My people tell me that American personnel were indeed present in Victoria in 1966.
"Some in connection to Hibal, other personnel were involved with classified military projects around Australia. ( Westall?)"As per our previous correspondence, I still believe that the Westall incident was tied in with other UAP sightings preceding and shortly following April 6, 1966."Unfortunately, as discussed, so much stuff was selectively “lost” or “destroyed” by military & government agencies during project transition."If you are in touch with Keith Basterfield, I have no objection to you passing on any information. Your call…... although the above doesn’t reveal all that much.Same with Shane Ryan and Rosie Jones."So thats my informant's take on HIBAL & Westall.
