Capt Wooblah; back in around 1983/83 just after Ah Kia's prang at Kampung Subang, a few top and mid level management pilots were ordered to attend a hush hush meeting ( actually nothing to do with safety; more to do with
PR with news media and insurance people ) where snippets of the CVR recordings of MH 653 were played. Snippets because they were not continuous playback ( some stuff has been snipped off ). One of the snippets I believe contained the 3 shots mentioned. The attendees would be very reluctant to tell more because people could figure out who they were. As I said the meeting had nothing to do with safety but how to cover arses if foreign press or insurance people started asking difficult questions. Until today, I still can't fathom the rationale of playing the snippets to the attendees except to hold them captive to something sinister!
