Just heard that the first plane was allegedly a 767 that had taken off from Boston........The second plane looked on the replays to be similar in appearance....Size is hard to determine....767---737??? They're different sizes but have similar shapes.....wing mounted engines well droppes and a largish tailplane surface........My first thought on seeing the second was a 737...

Terrible situation for the rescue people.....both are over 60 floors up........
