Vickers VC-10, The satisfaction of setting half the car alarms off in long stay carparks at the airports would be great when taking off :P haha
Boeing 757-200, My fav, Love narrow Bodied Airliners, Also the RB211-535E4B's make them hotrods, And they look great in just about any livery and the cockpit avionics are nice.
Airbus A321, Flymonarch Preferably, with the CRT Glass cockpits, and hearing those 2 IAE V2500's spool up from inside the flight deck.
Boeing 737-300/500, BMI Baby, Love those lil critters.
Flybe Embraer 145's, Love the ERJ145 flightdeck, and that lovely HYD noise when the engines are running at idle, Also AE3007 Spools are lovely from inside
Mike.
