Lockheed Electra 10E Special - NR16020

Joe Gurr: "The airplane, a Lockheed No. NR 16020, was really fascinating. It was obviously engineered and equipped for very long non-stop flights. The fuselage was solid gasoline tanks, two rows of them, from bulkhead to bulkhead, with just enough room between the tops of the tanks and the overhead for a person to be able to crawl from the stern to the cockpit on their tummy. Located in the stern, just opposite the main entrance door was a small table for the navigator's use. The radio transmitter was installed above this table. Jammed in what space they could find was a toilet."

"Gurr's recollections do not correspond exactly to what is known about the aircraft: there was just one row of tanks, the transmitter was below the table, and the toilet was in a standard location."

Lockheed Electra 10E Special at Burbank, California on May 21, 1937 just prior to the departure of the second world flight attempt. Noonan can be seen beside the open trunk of his Terraplane roadster. His wife, Mary Bea, stands near the front of the car. Amelia is talking with someone near the cabin door of the airplane.

Windows come and go

• "As delivered in July 1936, the airplane had only two windows in the cabin. These were the aftmost standard airline windows and were directly opposite each other. Then in January of 1937 a window was installed in the cabin door on the port side and a larger-than-standard window was installed on the starboard side. This last window is the one that was later skinned over in Miami."

Weight and Fuel Capacity

The License Authorization says "Weight empty as equipped 7265 lbs. (see equipment reverse side)."

On the reverse side it says, "Gas tanks: 6 in wing @ 394 gal. 6 in fuselage @ 754 gal." That's a total of 1148 gallons.

This was when the airplane was registered as R-16020 and it was sometime before 27 November 27 1936 when the total fuel capacity was increased to 1151.

At the bottom of the reverse side of the License Authorization it says:
