British North Greenland expedition

Gravimetric and seismological surveys were made, and radio wave propagation was also studied from their station codenamed "North Ice".

The expedition team consisted of 25 men; fifteen from the armed services and the merchant navy, nine civilian scientists, and a Danish army officer.

[3] Commander Simpson then led a party on dog sleds to establish the North Ice station about 230 miles (370 km) to the west.

[4] Once the party arrived at the site of North Ice, their stores and equipment, more than 86 tons of it, were air-dropped from two RAF Handley Page Hastings transport aircraft, flying from Thule.

Three members of the crew were injured, and sheltered in the intact fuselage of the aircraft until air-lifted out by a Grumman HU-16 Albatross of the United States Air Force.

[6] The expedition suffered its only fatality in 1953, when Captain H. A. Jensen of the Danish Army, a qualified surveyor, fell to his death on a steep snow slope.
