Fly an Airplane

[shcKr-]

I know how to use the direct fire mode to take off, and also shoot in this mode, but obviously when the plane is in the air i can come off direct fire and use the point and click to make the plane fly to that spot and circle.
But can you also use the ground fire option to make it attack the ground, as i have tried this and cant get it to work.. but in theory it should.

if not, is there a way to lock the camera behind the plane?
