I'm not sure about the fastest free fall part--how is free fall defined for purposes of this record? In particular, how does the record not belong to Bill Weaver, the test pilot whose SR-71 disintegrated at Mach 3.18? Here's his account of the incident: http://www.barthworks.com/aviation/sr71breakup.htm |

Freefall is generally defined in terms of vertical speed.
If you exit a DeHavilland Twin Otter that's doing 90 knots forward speed, yes, you get "forward throw" from the plane...but you still have to accelerate vertically before reaching terminal velocity. As a skydiver flying on your belly in an arched position, you usually fall at ~5 seconds per 1000 feet...excepting the first 1000 feet, which takes ~10 seconds to fall as you move from 0 vertical speed to 120mph.
(It's that age-old physics problem of whether the forward speed of a projectile has an effect on its downward velocity.)
