The Project Y "Spade" or "Omega" full-scale mockup, circa the second half of 1952
The mockup is shown above arranged in its vertical takeoff attitude, supported by a wheeled strut that retracts into the dorsal (top side) fairing behind the cockpit. It is unclear whether the underside fairing contained a similar strut.
Front view of the mockup pivoted into cruise attitude. Details of the shallow upper and lower engine inlets are visible, as are the apparently identical upper and lower canopy fairings.
