I was flown with my B47G3B1 from 1'400ft up to 15'700ft
bet you didn't shut it down
If you want to see spluttering around a '47, then the best thing to do is stick around when the engineer has fitted a replacement amc, that was sent AOG (ah yes, remember that old term of long gone respect), but the gadget was dispatched in a non pressurized cargo hold. heh hehe
