2311 Landed.

 

DURATION – 61 HOURS, 21 MINUTES

“Throughout the flight no mechanical trouble was experienced except for the elevator wheel partially seizing. The dynamos will not charge under an air speed of 30 knots, and, in consequence, lights could not be used in the car for more than a few seconds at a time, and when the ship landed there was not sufficient current to work the engine-room telegraphs. It is considered that this question should be investigated as soon as possible, and either more batteries be carried or dynamos be made to charge at lower speeds.

The crew were living on half rations practically the whole time.”
