Holger Hoiriis or Højriis in Danish (1901–1942), was born in the Brabrand area, Denmark, but emigrated to the United States, where he became a recognized pilot in the 1930-1940s.
[3] With the approach of World War II, Hoiriis became the first wing commander of the Delaware Wing Civil Air Patrol,[4] whose core mission, was to patrol the east coast of the United States, trying to find German submarines.
He did that very effectively and was the first to introduce defined search patterns, so that all of the Delaware coast was patrolled.
[4] He died in 1942 of complications from typhoid[6] and was interred at Laurel Hill Cemetery in Philadelphia.
[7] Through this work with barnstorming, he met Otto Hillig, who was a noted photographer and pioneer of aerial photography.
On 24 June 1931, the couple took off from Newfoundland in their red and silver / white Bellanca Pacemaker, with the name Liberty painted on the side of the plane.
Liberty was the name of the small town in New York state where Hillig lived and had earned his money.
Early in the morning, Hoiriis dived the plane down through a hole in the clouds, and there was the earth.
About 50,000 people were in Kastrup Airport, including Hoiriis's mother, and two of Hilligs friends from Liberty.
