Later in the autumn the Government bought some new machines for the battalion. In one of these, a two-seater Nieuport monoplane, with a fifty horse-power Gnome engine, Lieutenant Barrington-Kennett made a record passenger-carrying flight. On the 14th of February 1912 he flew 249-1/2 miles in four hours thirty-two minutes. In a rapidly advancing tide every wave makes a record, which is obliterated by the next wave. But the use of the word 'record', so frequent in the annals of aviation, does convey some sense of the exhilaration of the pioneers. Another of the machines supplied by the Government was a Breguet biplane with a sixty horse-power Renault engine. 'It was a most unwholesome beast,' says Mr. Cockburn, 'with flexible wings, steel spars, and wheel control.' It required enormous strength to steer it, and was perseveringly and valorously flown by Lieutenant Hynes. There was also a Deperdussin two-seater monoplane, which Captain Fulton flew; and the earliest of the B.E. machines from the Aircraft Factory, which fell to the lot of Captain Burke. The battalion was much impressed by the number of instruments fitted to their new machines. In the machines they were accustomed to there was nothing but a revolution counter, and sometimes, though not always, a compass. If the pilot's scientific ambitions went beyond this simple outfit, he carried a watch on his wrist and an aneroid slung round his neck. The risks that these early pilots cheerfully faced at the call of duty were serious enough, and it is surprising that their casualties were so few. The only fatal accident in the Air Battalion was the death of Lieutenant R. A. Cammell, R.E., who was killed while flying a Valkyrie monoplane at Hendon on the 17th of September 1911. The machine was not familiar to him, and it is believed that he forgot to work the forward elevator; at the height of about ninety feet the monoplane tilted to one side, and fell with a crash. Lieutenant Cammell was one of the pioneers of British military aviation. So early as June 1910 he had been sent to France to take over a Bleriot machine. He attended the Rheims meeting of that year and sent home some valuable reports. He was a daring and skilful aviator, and had qualified also as an airship pilot.
