it was apparently an older plane, which only has 30 mins of tape. Therefore, if you take into account the time it takes to land a plane and turn everything off, at MOST it would take you back to the point at which they realized their error and turned around (but I think they have stated that it doesn't even go back that far)

The Concorde did. But at 450 mph it would be 20 minutes.....and most planes travel above 500mph....so my math was a bit off. DD
