The Ålvand Allied bomber crash refers to the shooting down of the Allied Avro Lancaster PB202 by a German night fighter over the small lake Ålvand, in the heathland east of Nørre Vorupør, Thy, Denmark, on the night of 29 August 1944.

[2][3] It was previously thought that the downed bomber was first hit on its return flight by anti-aircraft artillery at Lyngby Battery, located on the coast ~10 km south of Vorupør, Thy.

However, later investigation showed that the bomber was instead first hit on its outbound flight by shots fired from a radar-equipped German night fighter over Lodbjerg (slightly further south on the Danish west coast).

A small Wassermann-S radar at Thyborøn (on the coast south of Ålvand) pinged the Lancaster on the night of the crash, as did an installation at Hjardemål (inland, to the north-east).

In flames and rapidly losing height, it passed low over the farm Udemark by Førby Lake, 2 km east of Nørre Vorupør.

The same plot also contains the remains of an unidentified British soldier, who was washed ashore on the beach near Nørre Vorupør in Autumn 1944.

He was initially buried on the shore by the Wehrmacht and was then, following the German surrender, exhumed and moved to the churchyard by locals on 14 June 1945.

The photoflashes left several craters at Koustrup Møllegaard; during subsequent summers, workers at the farm were tasked with filling in the holes when there was no other work to be carried out.

Agnes Møller (born 1909), who lived on the farm at the time, wrote of the bombs in her memoirs:[11] It was a strange experience.

The whole farmhouse had taken a serious shaking, so later on the plaster ceilings fell down all over the place, and the bands that held the roof tiles were either hanging loose or had broken.
