Here's one for the Spotters around Stansted:
Seen on Saturday pm while taxying in: an unidentifiable/unusual blue and white, turboprop single parked in the Compass Swing Bay. Looks like a research or Experimental aircraft, small slim fuselage but long slender wings (estimated at about 50ft span, high-aspect ratio) and large, tall fin/rudder. The type of layout for high altitude or very long range flight. Engine looks to possibly be a Garrett (Honeywell) unit and 4-blade prop with blades in ground fine pitch (hence the engine guess). Tricycle Undercarriage with mains retracting into pods in the wings.
Any info, I'm really curious!
