Bollyn mentions the crossing of AA11 and UA175 ground track baths.
As it turns out, several more aircraft converged with AA11 and UA175 over Stewart air base on that day
The blue boxes below show mp4 videos of the four routes.
The violet boxes below show altitude at roughly the convergence location for the four flights
Interestingy, although the AA11 transponder was out, so altitude was not available for the duration of the flight,
Also interestingly, track 5646 does a little jog in its ground track, in seeming coordination with the change in ground track of UA175
Stewart Air Base is to the far left center of the lower(violet framed) images
The table at bottom shows altitudes and time in seconds from crossing of AA11 at convergence over Stewart field.

of AA11 and UA175.

it WAS available
at the exaact intersection of the AA11 and UA175 ground tracks.
Is this all coincidence?
