I'am glad that someone, the Vietnamese, are looking on land too. I always
thought that by now if the plane had crashed in water, some debree which floats,
would have been discovered. Crashing on land in some remote dense jungle seemed
like a possibility. Also, the plane seemed to change course, so if it flew very
low and below any radar, it actually could have landed somewhere too. If it did
go down in the ocean, it probably went straight down and didn't leave much
if any debree behind, but eventually some residue will begin to float to the
surface and be found on the shores of Vietnam or someplace like that. And a lot
of remote islands in that part of the world. Maybe this will become a real life
episode of the TV show Lost.
A key item in this mystery is what is called the aircraft transponder. For
those unfamiliar with such a device check out aircraft transponder on Wikipedia.
So is a video is responsible for the plane going down?
