Planefag here
There are two issues that I have not seen properly addressed and really bother me.
1 - The aircraft was filmed doing aerobatics which create g forces and yet Russell (supposedly the pilot) did not appear to be straining while talking to the tower. Pulling g's make it hard to talk clearly even if you are trained.
2 - Another anon pointed out that 'bitchin betty" - the cockpit alerts systems - were not heard in the background while the plane was performing the aerobatics close to the ground. Bitchin betty would have been screaming about just about everything we saw on the video.
I have a portable air to ground radio to use as a backup and could talk to the tower ( or other aircraft) safely from my office if I wanted to.
It really seems to me that the cockpit recording was NOT from the person flying the plane.
Anyone else have the same concerns?
