Has the destruction of soviet tanks in Libya proven that tanks are now obsolete?

A single aircraft takes a ton of back up to keep it in the air, Its vulnerability is in the fuel supply and spares, ground crew and airfield etc......Its a Hell of a lot to organise and in most cases relies on the cooperation of other country's. A small well trained force on the ground could easily take out a mess hall full of pilots with a hand held rocket.....Destroy the aircraft and its back up at the roost....Problem over. Everything is vulnerable.
