I can see how this scenario has been presented by the media (per witness descriptions) but from what I have gathered, the Baron never got close enough to any other aircraft as to require such drastic maneuvering as a "pull up.." Pull up to severe stall (resulting in a fatal nose dive) from what exactly? Nothing? I am thinking that the Baron pilot (albeit tragic) really screwed up here.

The only reason I can see for major pull up resulting in a complete power on stall would be if there was an imminent collision. This was clearly not the case in this situation. This makes no sense to me unless aircraft missed each-other by a matter of feet.

Until the NTSB initial report comes out...
