Reply #76: Don't be so quick with "impossible" [View All]

Basically, you understand me correctly. One plane departed under the UA175 callsign (when communicating with ATC/FAA), another one - with tail number N612UA - under a different callsign. N612UA changed its initial callsign UA175 to something else and never changed back. So the "swap" was being conducted at Logan Airport already.

Did ATC wonder where that plane (N612UA) went? Well, let's ask Associated Press from 9/11/01:

A Boeing 767 out of Boston made an emergency landing Tuesday at Cleveland Hopkins International Airport because of concerns that it may have a bomb aboard, said Mayor Michael R. White.

The plane was sitting on a runway at the airport's west end with approximately 200 passengers on board. The mayor had said earlier that the plane was being evacuated, but an airport spokeswoman said the passengers remained inside.

It was unclear whether any passengers had been taken off the plane. A SWAT team and bomb unit were at the scene. However, White said, "As of this moment we do not know that this plane is in stress or duress."

The airplane landed at about 10:45 a.m., but the airport released no information about the plane's intended destination. Normally, planes of this size do not land at Hopkins.
