Thomas Christian Sneum was a Danish flight officer who was among the first British agents in Denmark during World War II. His most spectacular achievement was when, in 1941, he photographed two German Freya radar stations on Fanø. In the night of 21–22 June 1941 he and pilot Kjeld Pedersen made a spectacular escape from Denmark to Great Britain in a D.H. Hornet Moth. This would later inspire Ken Follett to write his novel Hornet Flight.
