I have been a keen advocate of using video recording devices in the cockpit since watching the TV series Air Disasters. I know many pilots are not keen but ‘safety’ is the key issue here. Video has been used in all space programs and it would certainly add value when trying to understand what was happening in the cockpit during emergencies.
As you may know, AVweb polls are extremely influential. Just last week, AVweb readers prevented the appointment of someone who had claimed to hold a commercial pilot certificate (but never did) to be the new head honcho at the Federal Aviation Administration. Or maybe I got that wrong.
I am sure we will have cameras and live Youtube streams from the cockpit of every commercial flight cockpit out there, before the week ends!
Voting booth is still open! 
Why was the landing gear not retracted—should be raised within seconds of rotation (positive rate, gear up)? Just maybe non flying pilot inadvertently reached for fuel cutoff switches instead of gear handle, but didn’t really realize it. In fact he denied it. But the other pilot saw the result immediately and said so. Might have been intentional or just a brain fart! Sometimes we do the wrong thing without really realizing what we did! Yes, a video would’ve captured the action, but not the reason for it.
