On 2 November 2007, another F-15C from the 131st crashed in Mark Twain National Forest near Boss, Missouri. No property was damaged and no people on the ground were hurt, however the pilot broke an arm and a shoulder, despite ejecting from the plane. The pilot also was said to be in "shock" by the landowners who found him. After investigation, the crash was attributed to a flaw in a part of the plane's fuselage; this led to all F-15 aircraft being grounded between November and January 2008. After the accidents, the 131st's flights were reduced, which was also due to the wing's transition to flying B-2s.
