"I normally like to end a flight in one piece on a runway"
I do too now but when a bit younger I took off about 600 more times in the likes of Beverleys, Hastings, Dakotas, Argosys, C130's, Twin Pioneers, Chinooks (even a DH Rapide) etc than I landed on a runway. I often wondered if it would become possible to arrange to jump out of a passenger plane near one's final destination, but the idea did not get far!
Once a bunch of us with some SEAL's took off from Glasgow airport in a military C130. The civilians in the terminal cafe wondered who these people were dressed in scruffy camouflage over wet suits and carrying shotguns etc were doing. Also the check in people wondered why we said we could fill in no landing airfield!
If this Wave Rider works I would love to go to Oz in one.
