The most important part of the test pilot’s job is the testing of prototypes, or first machines of new types of aircraft. He has not only to assure himself that the aeroplane is right in every particular, but he has to be completely satisfied in his own judgment. In other word, he must know that the new type is not defective in any way.
The three types of airship, rigid, semi-rigid and non-rigid are the outcome of the solutions by airship pioneers of various early difficulties. One of the chief obstacles that had to be overcome was the problem of attaching a car to a streamlined gasbag, making the car a reasonable length yet adding as little as possible to weight and resistance.
The distinction of having been the first British aviator to make a controlled flight is held by Lieut.-Colonel J. T. G. Moore-Brabazon. This chapter provides biographical information on Lieut.-Colonel Moore-Brabazon.
The first non-stop flight from the New World to Europe, the historic achievement of the late Sir John Alcock and Sir Arthur Whitten Brown. This chapter describes their superb feat of when, in June 1919, they flew a Vickers Vimy biplane form St John’s, Newfoundland, to Clifden, Ireland. Through fog and sleet, they flew 1,960 miles to make the first direct, non-stop flight across the North Atlantic. This chapter is concluded in part 5.
RIDING AT HER MOORING MAST at Cardington, Bedfordshire, the British rigid airship R 101. This airship marked several departures from previous practice. Her five engines were Beardmore Tornado heavy-oil engines working on the compression-ignition system. They provided heavier than had been estimated and an additional gas compartment was incorporated to increase the lift, giving a total capacity of 5,500,000 cubic feet and a final length of 777 feet. The R 101 was wrecked in France on October 5, 1930.

GRAF ZEPPELIN at Frankfurt-am- Main, Germany. Launched in 1928, the Graf Zeppelin ha many remarkable performances to her credit, including a number of cruises to South America and a flight round the world. She is 772 feet long and has a maximum diameter of 100 feet, her capacity being about 3,710,000 cubic feet. The German type of transporter mast will be noted.

THE INTERNAL STRUCTURE of the R 101 consisted of fifteen main longitudinal members with as many intermediate longitudinals between them. The main transverse frames, of which there were also fifteen, were of deep triangular section. Steel tubing was extensively used.
