Patuxent River Naval Air Test Center (NATC), September 1950 Static Display
Clockwise from the facing airplane on the left-hand side of the ramp:
McDonnell F2H-2N Banshee (note the elongated nose)
Grumman F9F-2 Panther being flown by Electronic Test
North American AJ-1 Savage
Pratt & Whitney-operated, civil-registered JB-17G (Ron Lewis: See http://www.nationalmuseum.af.mil/factsheets/factsheet.asp?id=2455) with an XT34 turboprop engine in the nose (the T34 was a Navy program but no production resulted for Navy airplanes)
Martin P4M Mercator (Almost certainly BuNo 122208; per Ron Lewis, see http://www.vpnavy.com/vp21_aircraft.html for other pictures of this airplane)
Douglas XF3D-1 Skyknight*
McDonnell F2H-2 Banshee
Vought F7U-1 Cutlass
Grumman F9F-2 BuNo 122563 with photo registration marks
Vought F4U-5P Corsair
Does anyone have any other information about these specific airplanes (particularly the Panther with the X on the fuselage) or the event?
* I had identified the Skyknight as an XF3D because of the small tail bumper (the production airplanes had a bigger one that incorporated a small wheel). Sharp-eyed viewer Ron Lewis noted that and also that part of the BuNo was visible, a 4 and a vertical line that could be part of a 1. Digging further, I'm all but certain that this is XF3D-1 BuNo 121457 that had just arrived at Pax for evaluation of control system modifications accomplished by Douglas.
