Chopper 4 is the longest live broadcast before the south tower's explosion that starts around two minutes beforehand. If
flight 175 was really involved, it would have been filmed way behind and (southwest) right of the towers at some point during its descent. It
had to fly just northeast/past the statue of liberty making a hard right and left turn into the southeast corner. None of this occurs because there was no plane, but
a very small orb that floats for less than ten seconds before disappearing behind the towers. It
leaves a very distinct shadow in the final seconds before explosion which proves that it literally circled around the south tower before bumping into it.
It becomes visible at 2:14 on top right of screen.
The 911 commission, properly and logically concluded that 175 had to fly over New York Bay in its final seconds, therefore,
any object seen west of the towers could not be flight 175. The shadow between the towers seen in three broadcasts is that of the drone, because it
logically and officially could not have flown east of Tower 1 in its final 3-5 seconds, which is required to create the shadow.
