Tartare, I would imagine they filmed it from the open ramp of a Herc. I have been on board RAAF Hercs on similar photo sorties with Hornets and other Hercs before and judging by the speed I would say that is the case here. It takes some skill on the part of the following pilot.
The best I have seen (I was not on board but have seen the photos) was a Kiwi Herc so close, it looked as if its cockpit was underneath the tail of the photo ship!
