No he didn't. That guy landed on a boat for more fuel in the middle.
He also was skimming the surface. Flying straight takes much less fuel than gaining altitude.
Only ones I know of that fly at any real altitude are the jet powered wings, and they are launched from a plane and parachute when they run out of fuel. And they carry a lot more fuel than the guy who crossed the channel did.
Sorry, he flew 10 miles on a tank which still means 3000' is trivial. It's basic math and if the guys had wings I think the pilots would have seen them depending on how strong the mushrooms they were eating were.
