The 2010 Alaska C-17 crash occurred on July 28, 2010, when a United States Air Force military transport plane crashed on Elmendorf Air Force Base in Alaska with the loss of all four crew aboard. The aircraft involved was a Boeing C-17 Globemaster III (tail number 00-0173) and the crash is believed to be the first fatal accident involving a C-17. The crew were preparing for Elmendorf's Arctic Thunder Air Show, which went ahead three days later as a tribute.

The aircraft was a four-engined C-17 Globemaster III built by Boeing.[1] It belonged to the 3rd Wing (3 WG) and operated jointly with the 176th Wing (176 WG) at Elmendorf AFB, located near downtown Anchorage.[2] The aircraft had Air Force serial number 00-0173 and was named Spirit of the Aleutians.[3]
The US Air Force has 199 C-17s in service with the active Air Force, Air Force Reserve and Air National Guard, with the type being based at Elmendorf since June 2007. At the time of the crash the base had eight of the aircraft, operated jointly by an active duty Air Force organization, the 3rd Wing's 517th Airlift Squadron, and an Alaska Air National Guard unit, the 176th Wing's 249th Airlift Squadron.[4] The mishap was the first fatal crash of a C-17.[1]
At the time of the crash on Wednesday July 28, 2010, the crew had been conducting a local training flight in preparation for the upcoming Arctic Thunder Air Show, to be held at the Elmendorf base over the weekend of July 31 / August 1. The C-17 is commonly featured in US air shows, highlighting its short take-off and landing capability. The plane had previously flown earlier that day with a different crew.[1]
On July 28, 2010, at approximately 6:22 p.m. Alaska Daylight Time (UTC-8) the C-17 took off from Runway 06 at Elmendorf Air Force Base to practice maneuvers for the upcoming Arctic Thunder Air Show.[5] After the initial climb-out and left turn, the pilot executed an aggressive right turn. As the aircraft banked, the stall warning system activated to alert the crew of an impending stall. Instead of implementing stall recovery procedures, the pilot continued the turn as planned, and the aircraft entered a stall from which recovery was not possible.[5] The plane crashed about two miles from the airfield.
Witnesses described a huge fireball, with one saying it looked like a nuclear explosion.[1] Anchorage Fire Department Captain Bryan Grella described how a fireball extended to around 750 feet (230 m) into the air, an estimated 2 miles (3.2 km) from Anchorage.[2] Debris from the crash was spread along 200 feet (61 m) of the Alaska Railroad tracks which carry passenger and freight trains daily through the base area, north to Wasilla, although no trains were scheduled to be passing through at the time of the crash.[1]
The crash killed all four crew members aboard, two pilots (both Majors) and a loadmaster (a Master Sergeant) of the Alaska Air National Guard's 249th Airlift Squadron, and a pilot (a Captain) of the active duty Air Force's 517th Airlift Squadron.[2] They were subsequently named as Majors Michael Freyholtz and Aaron Malone, pilots assigned to the Alaska Air National Guard's 249th Airlift Squadron, Capt. Jeffrey Hill, a pilot assigned to Elmendorf's 517th Airlift Squadron, and Master Sgt. Thomas Cicardo, 249th Airlift Squadron loadmaster.
Track repairs to the nearby railroad caused freight services to be suspended, and passenger services to be diverted by bus.[1] The air show went ahead as planned as a tribute to the four dead airmen.[1]
The investigation into the crash was released on December 13, 2010. It blamed pilot error, stating that the pilot's overconfidence in executing an aggressive right-turn maneuver led to a low-altitude stall and subsequent crash, despite the warnings correctly provided by the aircraft's stall-warning system, to which neither the pilot nor any other crew member responded effectively.[6]
As noted by several aviation commentators,[7] [8] [9] the crash presented significant similarities with the 1994 crash of a B-52 bomber at Fairchild Air Force Base, Washington. On both occasions, the local USAF's chain of command apparently failed to prevent the pilots involved from developing deliberately unsafe flying practices for aerial displays of large aircraft.
On September 23, 1995 an AWACS aircraft stationed at Elmendorf AFB struck Canadian geese on takeoff and crashed just 100 yards from the site of this C-17 crash.[10][11]
