F-104

Sorry, I meant BLC, here's the explanation from Wiki: The small, highly-loaded wing resulted in an unacceptably high take-off and landing speed, so a boundary layer control (BLC) system of blown flaps was incorporated, bleeding engine air over the trailing edge flaps to improve their lift. The system was a boon to safe landings, although it proved to be a maintenance problem in service, and landing without the BLCS could be harrowing.

Basically it added lift to the wings reducing the landing speed. Imagina a failure of one side wing's BLC during landing...many F-104 were lost for this. Also, the pilot had to mantain engine rpm high (around 90%) in order not to lose the BLC effect. The air for the BLC was taken from the 17th (and last) J-79 engine stadium.

what's a BLB failure?

Also the speedbrakes are out (if you look you'll see the typical "A" brace right after the wing trailing edge). I agree with tomcatboy, likely to be a gear-up emergency landing...at some 180 kts!!!!!!! :-O

Gear up emergency landing, perhaps?

Looks like slats & flaps are actually down.

There's something that doesn't convince me on this photo... Flaps are on Land position, a this ultra-low altitude a BLB failure would give the pilot NO time at all to even realize it!!!
