Says it all really...

This was the unofficial sticker for 8 Squadron of the RAF who flew the Shackleton right up until 1991, which was the final derivative of the Lancaster that first flew 50 years before, fitted with four Roll Royce Griffon engines, each with a contra-rotating prop or 8 screws. They had a friendly rivalry with 201 Squadron also of the RAF who flew the Hawker Siddeley Nimrod that was fitted with four turbofan engines or 4 blowjobs.
