Hi, i remember a read a Cold war book about i think it was an Avro Vulcan - i think - nuclear bomber in the 1960-70s which was given order to arm the bomb, but it was then ordered to disarm where the disarm mechanism failed, and the flight had to fly on until it was able to land somewhere in Kenya, where the bomb did not go off, because the airfield was higher elevated than the height where the bomb would automatically detonate. Can someone help me? Kind regards Daniel
