Parachute mine/Luftminen 24th october 1940 3 miles inland of Dover?

[frankiestein]

Hi Can any one tell me is there any Luftwaffe records of a Parachute Mine being dropped on the 24th October 1940, over the Martin Farm land area (approx 3-4 miles inland of Dover). There was an unexplained large explosion there. There was no crater, so an 'Airburst' close to the ground,probably via magnetic Fuse detecting the Farm machinery that it exploded over/in front of......at the time,assumed to be a Coastal Shell, but I have several pieces of evidence which by dimensions & details alone,are almost certainly to be parts from a German Luftminen/ Parachute mine in an area around the explosion site, so I'm pretty certain thats what it was. Not recorded as such, or very clearly at all by the british authorities at the time, but suggested at possibly a coastal Shell, or an explosive dropped by Bombers....................It is a fairly remote area, but directly under the flight-path of many Bombing missions etc.Maybe even a damaged Bomber dropping it into a field before attempting to turn back?? many thanks for any help
