Energia with Polyus (Skif D) lift off, near disaster, 17 May 1987

Another point of view of the first launch of the Energia rocket with the satellite Polyus (95 tons). In the very first seconds of the launch the rocket bents dangerously, it was due to specific implementation in the guidance software. This was made to avoid the rocket hits the service tower. For the next launch (with Buran this was changed). From:
