One last thing, on the first trip, Phil and I had to hand fly the aircraft the round trip as the auto-pilot was U/S. All shoulders to the wheel sort of thing.
Which is why I have the greatest respect for Canberra bomber pilots who flew high altitude, single pilot, no automatic pilot, no weather radar and and only one ADI and a turn and bank indicator to fall back on if the ADI toppled.
Bashing through the ITZ and among huge CB was normal SOP in some parts of the world. Add to that the propensity for high altitude engine flame-outs, then you have some highly experienced instrument pilots.
