The aviation industry, by definition of its products and their utilisation, is international. It may shortly become interplanetary. BOAC, by whom I am employed, operates its aircraft all over the world and employs staff in more than fifty countries. Our staff includes a very wide cross section of trades and professions, from aircraft cleaners to pilots, architects and lawyers, but with a few exotic exceptions, our industrial relations do not differ substantially from any other modern industry in the UK.
