Back in '66, when I was a young pilot on Shack conversion, we had a great, elderly gentleman navigator, name of Spike, who had spent most of his career in Bomber Command, and as a reward, was posted to 205 Sqn RAF Changi for his last tour.
We all survived the Sea Survival Course at RAF Mountbatten in January, jumping into the English Channel in just overalls and a Mae West - thank you Cox'n for the Pusser's Rum. A few days later, we had our first look inside a T4 Shack.
"Blimey!" said Spike "It's just like the inside of a Lanc - look, there's the Connell Box, and the Collimated Bomb Sight!"
It seems that not much had changed in 25 years. Spike said that even the smell was the same.
