Coff,
great pic of modern Funafuti. This is how it looked in my day, not quite the same.
No pax oxy on the 'K' and no drop down masks etc either. Drill was to descend ASAP in case of a decompression. First one I had was the doppler AE cover blowing out. Loud bang followed by white out and down we went scrabbling to don our masks.
Highest I have ever been in the 'K' was 35000 ft on a free fall para trial. Very cold up there with the ramp and door open.
