The Spirit of Kansas B-2 crash on 23 February 2008 marked a tragic milestone in U.S. Air Force history. Moments after takeoff from Andersen Air Force Base in Guam, the stealth bomber—valued at $1.4 billion—crashed and burned in what remains the most expensive aircraft accident in history. Fortunately, both pilots ejected and survived. This incident was the first-ever operational loss of a B-2 Spirit, one of the most advanced aircraft ever built.
The Crash: What Happened on the Runway
On the morning of February 23, 2008, the B-2 Spirit, tail number 89-0127, known as the Spirit of Kansas, attempted to take off for its return flight to Whiteman Air Force Base after a four-month deployment. Piloted by Major Ryan Link and Captain Justin Grieve of the 393rd Bomb Squadron, the stealth bomber had logged over 5,100 flight hours and was considered mission-ready.
However, shortly after wheels-up, a catastrophic failure in the air-data sensors led the flight control system to miscalculate the aircraft’s speed and angle of attack. The result was an uncommanded 30-degree pitch-up, causing the bomber to stall at low altitude, yaw violently, and crash with its left wingtip gouging the runway.


Investigation Findings: How Rain Condensation Took Down a $1.4B Aircraft
A U.S. Air Force Accident Investigation Board revealed that the crash was caused by moisture intrusion into three of the B-2’s skin-flush air-data sensors due to “heavy, lashing rains” prior to the flight. This condensation affected pressure transducers, which are crucial for providing accurate airspeed and angle-of-attack data to the aircraft’s fly-by-wire flight control system.
When the B-2 rotated for takeoff, false airspeed data showed a speed 12 knots higher than actual, prompting an early liftoff. Almost immediately, the flight control system switched laws and injected a dramatic pitch-up maneuver, thinking the aircraft was at a negative angle of attack. The resulting stall was unrecoverable at such low altitude. The crew ejected seconds before impact, and the aircraft ignited upon crashing, destroying the airframe completely.
Immediate Aftermath and Grounding of the B-2 Fleet
Following the crash, the remaining 20 B-2 Spirit bombers were grounded under a directive from Brig. Gen. Garrett Harencak, commander of the 509th Bomb Wing. He called it a “safety pause” while systems and flight protocols were reviewed.
A B-2 in the air during the accident was recalled mid-mission, and six B-52 Stratofortresses from Barksdale Air Force Base were deployed to fill the gap in Pacific operations. The full B-2 fleet resumed flying on 15 April 2008, nearly two months after the crash.
Damage Assessment and Historical Significance
The Spirit of Kansas crash caused a total loss of US$1.4 billion (approx. US$1.96 billion in 2023 dollars), making it the costliest aircraft accident in military aviation history. It remains one of only two B-2s ever lost, with the other being a 2010 B-2 fire incident that led to retirement, not crash.
There were no munitions aboard, but classified material had been loaded prior to the flight, according to Air Combat Command reports. One pilot was hospitalized, while the other was treated and released at Guam Naval Hospital.
Legacy and Cultural Impact
The Spirit of Kansas B-2 crash has been widely cited in defense and aviation circles as a case study in how sensor integrity and data fusion are critical to next-generation stealth platforms. It was featured in Season 22 of the Canadian documentary series Mayday (also known as Air Crash Investigation) in the episode titled “Stealth Bomber Down.”
The event also sparked discussions around maintenance protocols, climate effects on avionics, and the cost-risk analysis of deploying strategic stealth assets in humid or tropical conditions.
Conclusion
The Spirit of Kansas B-2 crash was more than just a billion-dollar incident—it was a pivotal moment for the U.S. Air Force’s most secretive and high-value strategic bomber. Though no lives were lost, the crash highlighted vulnerabilities even in the world’s most advanced stealth technology. It reinforced the need for redundant sensor systems, robust pre-flight checks, and weather-aware operations for elite aircraft in complex theaters.
