It is a gripping story that is told about the efforts made to make use of that stationary aircraft carrier in the middle of the Mediterranean. It is also poignant that Alec Guinness should play the part of a reconnaissance pilot because it is just this ruse that the British used to pretend that they hadn't broken the Italian and German ciphers thus enabling them to sink all the Gerry troop ships and always be just in time everywhere. A lame performance by the cast is diverted by the backdrop of a desperate situation on a tiny island that has been invaded by every great power since anyone can remember. If Ultra hadn't done it stuff these people would have been run over even though the Axis forces would have lost the war in the long run.
