He took the record for fastest freefall (supersonic), highest skydive and highest manned balloon flight. Pretty sure he'll be happy with that, and to let Kittinger keep longest freefall.
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.)
