Deliberate gear up landing for an airshow.
Really? That would be a very expensive and dangerous stunt to pull off at an airshow... Then again after the non existant airshow safety that surrounded the Su-27 (?) crash in the Ukraine (?) a couple of years ago, nothing would surprise me...
My bets would be: a test of some description, hence the footage...
...or: the pilot trying to put on a show for said cameras, trying to be a bit too "punchy" ("punchyness" is a big thing in the fast jet world) by raising his gear as soon as the microswitch would allow it, sinking back to the deck, realising he'd made a balls up, and deciding that his bobsleigh impression was probably the best way forward...
