The air age updated in our ally, Great Britain, is a story with implications for peace and war. First person reports by war time aces and peace time pilots, Lord Brabazon and Air Marshal Sir John D' Albiac, trace developments since the birth of aviation, record the record breaking flight of Peter Twiss in the Fairey Delta 2, in 1956 and report on medical aid by air in Australia. The growth of London Airport, paved with enough concrete to cover a two lane highway from London to Edinburgh and fictional accounts of smuggling and espionage are interwoven here. The photographs and diagrams are absorbing and the layout is attractive. Great flights, great planes, great pilots and the question mark of the future are posed in pleasant, briskly British terms which should interest many air-minded American teen-aged boys.
