Crash of the Crusader "In our last issue we reported the death of Mr. John Cobb, on the verge of triumph, when his jet-propelled speedboat Crusader disintegrated and sank in Loch Ness after reaching a speed of about 206.8 m.p.h.  This series of eleven frames from a ciné file may cast some light on the cause of disaster. Most observers of the event refer to a triple wave which met and struck Crusader, causing it to bounce and, according to some, to dip its nose in the third. These waves have been referred to as "pressure waves, " but one authority says they could not have been pressure waves in the technical sense and another authority suggests that they may have had their origin in some quite normal disturbance of the water. In frame (1) the air intakes (just ahead of the cockpit) are well clear of the water, although the nose appears lower than was usual at speed. In frame (2) a puff of steam appears at the intake and the nose is dipped. The puff becomes a cloud and the craft slows until at frame (7) an explosion appears to take place."
