The Boeing 707 started its takeoff run on runway 25 at 14:05. While accelerating through 80 knots, the no. 4 engine instruments indicated zero thrust followed by the no. 2 engine thrust reverser deployment light. The crew aborted the takeoff at a speed below V1 at 800-900 m down the runway. The plane decelerated slower than expected and veered to the right, until the no. 4 engine struck a pavement roller. The 707 caught fire and traveled another 260 m before coming to rest, engulfed in flames.

Probable Cause:

PROBABLE CAUSE: "Damage to reverse thrust system of No.2 engine, not discernible by means of cockpit instruments, and consisting in the disconnection of a duct with resulting lack of pressure in the pneumatic clamshell door actuating mechanism.
This malfunction allowed in the development of considerable forward thrust by No.2 engine even though the four levers were in the "reverse" position."
