A very remote, aptly named flat exposed area of granite, easily found by following the military posts north from Rough Tor. Whilst the outcrop is disappointing there is an interesting dispute about the location of Flat Tor.
The position of Flat Tor was misplaced for many years by the OS who had it at SX 603 807. This point is mentioned by Terry Bound in A to Z of Dartmoor Tors who also, courtesy of Helen Harris, supplies a correct grid reference. To the south-east of the tor there is a water filled pit the scene of an air crash.
We learn from Mr C Lloyd of Bristol (Dartmoor Magazine 15 Summer 1989 Letters to the Editor) that the crash involved a naval aircraft - a Sea Vixen - in May 1965. Both airmen escaped unhurt. Debris at the crash site can still be found.
