Air AmericaChristopher Robbins/Cassell, £7.99

THIS is the revealing inside story of the world’s most extraordinary covert operation.

Air America was a secret airline run by the CIA. It flew missions no-one else would touch, from the legendary Flying Tigers in World War II to two brutal decades cruising over the bomb-savaged jungles of South-east Asia.

The pilots dared all and did all – a high-rolling, fast-playing bunch of has-beens and hell-raisers whose motto was 'Anything, Anywhere, Anytime.

Reservations were not needed – just courage and a willingness to fly to the bitter end.
