Classic British Flight Sim

During the Second World War, he served in the Royal Air Force as a radar specialist and was involved in the early warning radar defence system which contributed to the RAF's success during the Battle of Britain. Clarke actually spent most of his service time working on Ground Controlled Approach (GCA) radar, as documented in his semi-autobiographical novel Glide Path. Although GCA did not see much practical use in the war, after several more years of development it was vital to the Berlin Airlift of 1948-1949. He was demobilised with the rank of Flight Lieutenant. After the war, he earned a first-class degree in mathematics and physics at King's College London.
