My best friend, who is summering in MA right now, lives in the neighborhood (Boca Grove) where the two planes came down. I live 5 minutes away. When I read the news on AOlL, I was shocked, for years the aiport has been fighting the city and neighboorhood to build a general aviation tower, this certainly will be the catalyst in that pursuit. Boca Raton Airport is a small one, no commercial service, mostly private jets, airplane schools, and biz jets. When IBM had its campus here (PC invented there!), there was a fleet of Leers stationed at teh airport doing multi daily runs to Westchester County Airport (near Armonk, IBM's HQ).
Yahoo says now 4 died, 3 in the Lear, 1 in the prop. The pilot of the prop attempted to jump out with parachute after the collision but apparently did not make it.
Like everyone else, I'm schocked and saddened at the loss.
