On the morning of May 31, 1944, two P-51 Mustangs likely collided due to bad weather. One aircraft crashed in Zandbergen and the other in Onkerzele. 1st Lt. Robert Homuth did not survive the crash and was buried at the American cemetery in Neuville-en-Condroz. Captain Carroll McElroy survived the crash but was taken prisoner of war by the Germans in Zandbergen. He died in 1995 and is buried at Arlington National Cemetery.
On September 2, 2013, Wings of Memory conducted an initial search, and on October 13, 2013, they succeeded in recovering the remains of the aircraft.
Some of it was transferred, via Chièvres Air Base (CHAPE), to the museum of the 335th Fighter Squadron at Seymour Johnson Air Force Base in North Carolina, the squadron to which both pilots belonged.

A monument for the two American pilots was designed by member Stefan Delannoit and erected by members of Wings of Memory, with the support of the city of Geraardsbergen.

On September 28, 2017, it was unveiled in the presence of a delegation from the 335th FS, numerous dignitaries, and relatives of the victims.
Two Belgian Air Force F-16s flew over the monument. A Stinson AT-19 Reliant flown by Remco Sijben also flew over the monument.

Mustang artifacts can also be viewed in our museum.
