And I may as well blab it because I don't think I have any hope of patenting it--and because I think the sooner it's put together by somebody--anybody!--the better. 
I was watching the news coverage of the aftermath of the NAS Oceana F-18 crash and how the newsies were saying it could take weeks to arrive at a cause of the accident.  I remembered that most military jets didn't have flight recorder systems as such, simply because they didn't have space for them.  And then I realized that the aircrew already were plugged into the plane whenever it was in operation.  The helmet headset.  Run a data feed from the aircraft's computer to a memory module in the headset and then there would be a flight datalog even if the crew ejects from the plane.  The module wouldn't have to be big...probably smaller than an iPod.
