The Nimrod has always looked like a parts bin special but the undisputed British Commonwealth All Comers title for the ugliest version of the Comet has to go to the Mk3 Nimrod... (the infamous AEW with schnozzles front and rear). Proof of the adage "If it looks right etc.."
When we (the Boscombe team) arrived at Woodford in '82 to start the flight trials phase, we had to pull our Sherpa off the peri-track as we were all literally crying with laughter at the sheer ugliness of the beast that we'd spotted lurking on the far side of the airfield.
