Incidentally John was the same age my son is now, really just a boy .

if anyone knew him personally I would really welcome a contact
Hi Sldm
Welcome to the forum and with a really nicely written post.
Yes the early ejection seats had a fairly powerful explosive cartridge (main gun cart) to clear the seat from the aircraft which could cause spinal and other injuries,the later rocket seats had a smaller main gun cart just to move the seat a few feet and then the rocket pack would fire and clear the seat well away from the aircraft.

regards LR

But I definitely flew it to Wroughton in about 66, and was told that was its last flight. Might possibly have been made serviceable for a last flight to St Athan. Anyone got the aircraft log book?

I made a very serious error whilst flying in the left hand rear seat in WT308 (what would normally be the nav seat, but the two B(I)6's we had had been modified for trials work, I was just a flight test observer). After shutting down I went to put the pins back in to find that the hatch wasn't armed. I'd flown the whole sortie with the explosive bolts disabled . . .

The seat rating was, I think, 400/400, i.e. 400ft minimum height AGL, 400kts minimum IAS. I can't remember a descent rate limit, but this was a long time ago, when WT308 and WT309 were still at Farnborough.

Does the B57 count as a Canberra 'variant'?

Works for me, a Canberra is a Canberra.
