Spiral Attack Maneuver Avoids Top Brass

The aircraft, coming from the north, crashed into the west block of the Pentagon by executing an 270 degree spiral, and descending 7 thousand feet in 2 minutes.

Dulles Air Traffic Controllers thought it was a military plane.

The west block of Pentagon was under renovation, and sparsely occupied.

No high-level officials were injured or killed in the attack.

The maneuver circling over Arlington meant additional exposure to interception.
