[Seaplanes]

According to my source (KTB Gen.d.Lw.b.Ob.d.M./O.Qu. for 27.May 1944), the aircraft was on a routine training flight south of Bornholm, when the starboard engine caught fire in 500 meters altitude. A forced landing was carried out, but due to wind and heavy seas, the plane was thrown up in the air and crashed on impact with the water after some 60 meters in the air. Three crewmembers were rescued by a nearby German submarine, Hptm. Kopp and Fw. Benders both dead and Obfhr. Hans Hagelstein unhurt. There is no mention of involvement of enemy aircraft.
This particular aircraft started service as K6+AL of 3./406 and was passed on to 1./Fl.Erg.Gr. (See) in Copenhagen on 31.05.1943 and became 6H+LH.
Some sources give the date of death of Hptm. Joachim Kopp as 23.06.1944.
