Roald Dahl flew planes in the Second World War (1939-1945) when Germany, Italy and Japan fought against Britain, France, Poland, other European countries, the USSR and the United States of America. Going Solo is Dahl's time with the RAF (Royal Air Force). He writes "I did not need to leave out anything here because every moment was, to me, totally interesting."
