For weeks now, the Air Force has remained tight lipped about an incident involving America’s supersonic heavy payload B-1B Lancer over Texas early last month, acknowledging only that an incident had occurred, and eventually, grounding the nation’s entire fleet of Lancers, citing an issue with the aircraft’s ejection seats.

Now, as the Air Force prepares to return the B-1B fleet to an operational status, new details have emerged about the heroism on display in the cockpit of the Lancer that conducted an emergency landing at Midland International Air and Space Port in Midland, Texas on May 1st — and although the story raises clear concerns about the status of the Lancer’s ejection apparatus, it also offers a powerful glimpse into the professionalism demonstrated by America’s military aviators when faced with difficult, and even seemingly dire, circumstances.

The flight began like any other, with the B-1B from the 7th Bomb Wing at Dyess Air Force Base in Texas on a routine return flight when a fire warning light popped on inside the cockpit. The Lancer’s four-man crew, comprised of a commander, copilot, offensive systems operator, and defensive systems operator, promptly set about moving through the engine fire checklist. Reports remain sparse, but it appears that the crew consisted of a senior commander and what may have been three trainees, though by all accounts, they executed the aircraft fire procedures without issue. The fire, located in the aircraft’s number three engine (closest to the fuselage on the right wing) continued to burn as they approached the final line on the checklist you can only reach if every previous effort fails:

Eject from the aircraft.
