re: B-17 collides/crashes with another plane at Dallas air show.

Loss of life is obviously tragic and the most important thing, but the loss of one of the last still flying B17s is sad too.

The smaller plane (P-51??) was in a hard banked turn and the underside of his plane was possibly obscuring the view. Not sure who controls airspace at an airshow - ATC or the show operators - but someone should have been spotting and radioed to help keep those planes apart, both altitude and across the ground.
