An RAF squadron is assigned to knock out a German rocket fuel factory in Norway, which is part of the Nazi effort to launch rockets on England during D-day, by flying up a well-defended fjord at low level.
A dynamic and multi-layered, based-on-truth RAF, drama, in which Cliff Roberston trains a squadron of top Mosquito pilots to bomb a Nazi rocket fuel installation up a Norwegian fjord. The clever bit is they have to bomb the cliff face above the factory and drop a million tons of Scandinavian granite on Jerry.
Some wonderfully worked out set-pieces and top-notch camerawork give it a real feeling of action and the audience get a real feel for the skies thanks to the first class stuntwork.
Over a splendidly vibrant score, the spectacular aerial photography still looks good after all these years (even if some of the ground-based drama betrays with the whiff of cheese.)
Old-fashioned granted, but great stuff.
