Odd airplane sighted at Heathrow

[Guest skylanepilot]

Just got back from a business trip to the UK where I spotted a really odd creation parked outside a Virgin hanger at Heathrow. Didn't have my camera, so no pics :-( ... but it looked like a DC-10 with a double-decker bulge on the front end of the fuselage (kinda like the "Guppy"). It was painted a hideous green .. which could have been primer.Anyone have any idea as to the identity of this oddball??

Could it have been a fire trainer? They're usually built to look like a 747 but with 3 engines.
