MARCH 25TH, 1948 FLIGHT 321 shadowing the approaching ships, but in the later phases thev changed their role and were flying anti-submarine patrols for the same ships' protection. The shadowing trips were of a V.L.R. order, each flying boat being air- borne for some 13 hours. The anti-submarine flights were much shorter—lasting only just over five hours •each. With a choice of either, I plumped for "an anti-sub marine trip as this promised to be more interesting, and also because on the previous occasion on which I had flown in a Sunderland it was with No. 201 Squadron on a genuine anti-submarine operation.

What a joy it was to be on board again listening to the old familiar cockpit drill and patter; one can only wonder at the complication and efficiency of it all. The captain of the aircraft was W/C. J. L. Crosbie. Wing Commander Flying at Calshot, and, since he has been flying Sunderlands for nearly ten years (he flew the prototype), it is not surprising that he is familiar withthe drill. I went with him from the stern turret forwards to the bow while he checked every little detail —even trying each porthole screw. Here is bi»t a small selection of the orders and com- ments which came over the inter-com. as we gently taxied over Southampton Water. When he took his seat the second pilot had already started the outer engines and moorings were cast off immediately. "Fuel to be used 714 gallons." (This meant that from our The radar operator in his tiny shaniy which is jammed in between the 2nd pilot's seat and the navigator's station.

Luck seemed not to be with us for a long while. There were alarms, of course, and each time these occurred throttles were slipped into '' auto rich '' and we dived down almost to sea- level.

On our request for further instructions we were told to return to base, thanked for our co-operation and informed that the result of the morning's exercise was the sinking of five out of seven of the attacking submarines.—J..Y.
