Even after 20 years, that blue sky looks very familiar, @FISH. That last hijacked plane flew across Pennsylvania, though not sure if it flew over Philly. Were you aware of it before it crashed?
The average Joe was NOT aware of the hijacked plane in PA. Our Mayor instructed for all buildings over 20 stories high to be evacuated immediately shortly after 10 AM. I was working in Center City Philadelphia. Seeing folks running out of tall building running to get home was like something out of a 1950's Sci-Fi movie.
There are 80.54 miles from New York City to Philadelphia PA.
There are 198.14 miles from Philadelphia to Shanksville PA.
At 9:28 a.m.: United 93 was hijacked.
9:57 a.m.: The passenger revolt begins.
10:01 a.m.: The hijackers decide to crash the plane
Jarrah again asked the other hijacker if he should crash the vehicle. This time, he was told, “Yes, put it in it, and pull it down.â€
Jarrah pulled the control wheel hard to the left, causing the plane to fly upside down, and then to crash into the ground at a speed of 580 miles per hour.
It was 10:03 a.m.https://www.history.com/news/united-flight-93-september-11-passengers-revolt-crash
