This could have been any day, and around 13:48 zulu time.
This could have been any training mission with a call sign of "Venus One Heavy", and ...
Why was this tape released on this day?,
I also find it very very hard to believe.
If you want more information, research weather information for New York City and find a day that the altimeter was 30.36 at 13:48 Greenwich Mean Time.
I'm an Australian, wouldn't know how...maybe another FReeper can research for that information?
