The very rare sight of seven full-size WW1 Fokker Dr.1 Triplanes replicas in the air together. Each of these aircraft is painted to represent one of the aircraft/pilots that flew as part of Manfred von Richthofen’s Jasta 11 in April 1918.This is apparently only the second time since 1918 that seven of these aircraft have been seen in the air together at one time (the first time was in 2007).
This amazing sight was repeated at the Classic Fighters 2013 airshow as well.
