Using air ,dives to about 40 metres are normal with decompression stop on ascending.Deeper than this requires mixed gas diving or tech diving as it is better known!At 37 metres you have 9 mins before returning to surface!!

If the priming pump reaches pressure and then starts screaming and strips gears could this be due to loss of prime?

my late father had a set of POW photos(he was army and captured near Tobruk)it seemed to me that they were for sending to familys ,most were formal pictures and varying in the number of people in them.Most of them appear to be a Scottish regiment and one is of a New year concert,I can scan and put them on iif anyones interested.

One on Ballykelly ex 204 sqdn appears to be 140in diameter,it was a bug..r to marshal a mk 2 shack onto!Also in bad condition and in the winter the mainwheels would be frozen in ice which took a lot of power to break free before it came hurtling at you!!!

I was twice on starter crew on shacks when the bomb bay load was “accidentally”dropped including (old)depth charges, sonobouys and 25lb smoke bombs!Second time had a torpedo amongst the other stuff .Obviously nothing apart from the smoke bombs went off!

If it happened here in Thailand in a “high end car”the driver would probably have pulled out an automatic pistol and shot them all!Road rage here is dangerous!!!

I did a few long transits in a shack MK 2 and our chutes were in a pannier in the bomb bay!Groundcrew by the way !Longest flight (I think I am correct was from BKY to El adem with just a few gallons left on arrival!!
