Testing of the .50 Cal guns on P-51 Mustang Twilight Tear. This aircraft is owned by Ron and Diane Fagen, and can be seen at Fagen Fighters WWII Museum in Granite Falls, MN. She is flown regularly, and was a Grand Champion winner at Oshkosh in 2009.

"Twilight Tear" is a North American P-51D Mustang with a rich history. Delivered to the 78th fighter group in Duxford, England in april, 1945, she arrived late in the war. She was assigned to lt. Hubert "bill" davis, who promptly named her after his favorite race horse. davis shot down three german aircraft, two ME-109's and, notably, an ME-262, Germany's first fighter jet. He also participated in the famous raid on Hitler's eagle's nest near the end of WWII. 

After the war, Twilight Tear, along with many other low time fighter aircraft was sold to the Swedish Air Force in 1948, then went on to serve in the Israeli Air Force from 1953-1960.

The aircraft was purchased in 1960 by Bill Lear of lear aircraft fame, was modified and saw civilian life as the demonstration platform for the world's first autopilot.

After crashing in Iceland in 1963, Ttwilight Tear was stored until acquired by an american in 1991. After a few subsequent transfers, it was acquired by Ron Fagen in 2005. While undergoing the restoration, the discovery was made as to the rich history and lineage of this famous aircraft, and the decision was made to restore her to her original specifications when Hubert Davis flew her inWWII.

This complete and meticulous project earned the prestigious "Lindy" at Oshkosh in 2009. The detail is unmatched, right up to and including the functional .50 cal machine guns! (see the video below)
