Saw vid and thought "one way to gain airspeed! Yeesh!...package check, hold on tight boys!", scrolled down and lookee here PJs beat me to it. A sheer drop-off that distance above forest, I'm thinking he'll only get one try...practice would be facilitated how? OK, lock brakes, jam throttle, full flaps and tuck 'er in sonny.
I guess leveling off qualifies as flying home once your internal organs catch up. I'd cheat with helium in those balloon tires.

"Tuck in" was a favorite joke on PCH/101, San Benardino/10, Grapevine trying to catch a car full of eyecandy IYKWIM, not too different than "Hotrod Lincoln". If we were on bikes it'd make sense and not be funny, I caught anyone I wanted on the Z1R, even the Sportster, but behind windshield of an El Camino? Priceless.
Still have the ElCO by the way, since 1970, legit second owner of Ol' '65 the Fleetside Ferrari. Not much motor, but 2.73 rear end, < 3300 lbs, wide ratio Corvette trans, lightweight dual disc flywheel running one disc, and suspension assimilated from air conditioned big block GTO's and Monte Carlo's. For awhile speed limit was 55 and it could; even initiate U-turns, literally.
