A look at the map will show how much longer a flight from, say, California to Japan is than one from Canada to England. There are several likely routes that might be tried in attempting to make such a flight. There is, of course, direct flight from America to Asia over about 4,500 miles of sea. A halt might be made, however, at a suitable inter- mediate spot such as Honolulu in the Sandwich Islands. In this case the direct water-stretches would be re- placed by two of about 2,100 and 3,400 miles. A third possible route would be to fly round the Ameri- can and Asiatic coasts, the only stretch of sea to be flown over then being the short distance across Bering Strait. This would involve a flight over a distance from 6,000 to 8,000 miles, depending upon where the flight commenced and terminated. ***** At the present time the record flight of a lighter- than-air machine is that of a Zeppelin during the war which flew 4,000 miles in 100 hours, and of a heavier- than-air machine that of the Vickers-Vimy which crossed from Newfoundland to Ireland, a distance of about 1,900 miles. Considering both radius of action and reliability, the authors consider that the rigid airship stands first, the non-rigid second, and the
