Hughes had several Douglas A-20G Havocs modified as company transports and one was used to test the XF-11 fin and rudder. Another became chase plane on the flight of the XF-11. NX34320 shown was Hughes' personal aircraft.

The 8-engine Hercules NX37602 moored on the water, its great size apparent from the comparitiveiy small size of the 25 ft long nacelles of the 28-cyl engines. Its tail plane span was 10 ft greater than the wing of a B-17 Fortress and nothing like it had ever been seen before, or for that matter has been seen since.

An airship overhead casting its shadow, the H-4 Hercules is once more on the water after Hughes' death in 1976, when it was moved to a purpose-built dome. At the end of 1998 it was moved 400 miles up the west coast in a 5-day operation by an ocean-going tug to Astoria, then by road in five sections to McMinnville, Oregon, where it has been reassembled for display in a new building, commencing in 2000.

Howard Hughes in his soft felt hat about to taxy out the XF-11 prototype for its first (and last) flight with the cooling gills of the huge 28-cyl 4-row radial engines open to avoid overheating.

Hughes takes off in XF-11 44-70156 with 4-blade propellers. As on the flight of the first prototype he does not carry an observer, but this time nothing goes wrong and the initial tests are completed successfully.

The Hughes XF-11 Long-range Photographic-Reconnaissance Monoplane (two Pratt & Whitney R-4360-13 engines).
The XF-11 prototype 44-70155 pushed out to show its 101 ft 5 in. span high aspect ratio wing, twin booms and two man cockpit in the central nacelle. The fairings under the outer mainplanes were racks intended to carry 300 gal long-range fuel tanks but these were never fitted.

This view of the first XF-11 shows the 8-blade contraprops and the almost full span flaps lowered to the take-off setting. The ailerons were small as they were combined with spoilers for lateral control.

38 examples of the B-23 Dragon bomber were built and 12 converted to C-67 transports as 39-047 shown. Over 20 were sold postwar and Hughes purchased several as company transports.

Hughes' B-23 transport conversion N52327 was preserved with the USAF Museum and is seen here at McChord Air Force Base in 1995. The Hughes modifications include a new nose and de-icing boots.
