Crew mistakes and inadequate safety standards led to the crash that destroyed a $450 million B-1B bomber, an Air Force probe found

• A B-1B Lancer crashed at a South Dakota base on January 4 after missing the runway by just 100 feet.
• The heavy bomber skidded about 5,000 feet and caught fire, causing about $456 million in damages.
• Poor weather and a lax safety culture at Ellsworth Air Force Base led to the crash, a probe found.

A B-1B Lancer valued at more than $450 million that crashed in South Dakota at the start of this year missed the runway by 100 feet, a mistake accident investigators attributed to the aircrew's shortcomings as well as the poor training culture within units at Ellsworth Air Force Base.
