Hi all,
Here is a graphic illustration of the current state of the USAF. These accurately modeled video graphic simulations shows the breakup sequence of Mick-2's structural failure at close to 450 knots. The pilot survived the unstable ejection, but with significant injuries. Severe fatigue cracks in the main structural longerons of the early block F-15 (A, B, C, & D models) forward fuselage are responsible (E model Strike Eagle variants are not affected).

The F-15 fleet was grounded after the mishap. Initial investigations
revealed a structural failure in longerons common to all F-15A/B/C/D
aircraft, but not the F-15E (Strike Eagle). All except the F-15Es were
grounded from about 3 November 2007 until 8 January 2008. Further
investigations revealed that about 180 F-15s have longerons that do not meet
the original blueprint specifications for thickness and strength. Those
F-15s remain grounded, and it is not known if they will ever fly again.
The two links below are computer generated animations of the call sign Mick2
F-15 inflight breakup during November 2007. For those who aren't familiar
with the incident, two F-15Cs from the Missouri ANG (St. Louis) were
conducting BFM (Basic Fighter Maneuvers). The start of the mishap maneuver
was a 9000' offensive perch with rapid onset of G. During the engagement
Mick2 felt unusual "fishtailing" and saw dust in the cockpit. He rolled
wings level to investigate. Shortly thereafter the cockpit separated from
the remainder of the aircraft. The pilot in Mick2 managed to eject, but
suffered significant injuries due to the unstable ejection.
