Just one GoPro4 HD stick on the wall in the pilots cabin could say more in the minute then 1 month investigation by the best NTSB experts.

Well , next time we post GOPRO video from our wind/ kite surfing session on Youtube could consider just posting sound track only.
So much more fascinating since we could imagine now everything when hearing water splashing sound ....
