B-17 Startup Sequence and Flight From Inside 

This is a no frills video, giving you an idea on what's its like to fly inside a B-17, from Engine Start to actually what you will see and hear as it flies from Santa Fe, NM to Scottsdale, AZ. Filmed on 4/13/2012
Barely seen is a P-51 pealing off at the 5:30 mark.
More than half this video involves the start up tasks so if you want to zip ahead to the flight, jump to the 5:00 mark.
