So I call my 6yr old son outside this evening (7 July 2011) at about 9:05pm.
It was traveling about SSE and was CLEARLY a very large 4 engine airliner. I couldn’t even begin to estimate the altitude, but he wasn’t on approach to anywhere.
And I was surprised at how little noise it was presenting (I live 15 miles south of Scranton PA and a major air route goes overhead our house and they always seem to travel SSE).
My guess was 747 - FlightTracker showed NOTHING. At least no 4-engined airlines.
