Key Takeaways:

The NTSB concluded that the pilot and passengers of the unresponsive small aircraft that flew over the U.S. Capitol were likely incapacitated by a lack of oxygen due to a loss of cabin pressure.
The aircraft, a Cessna 560 Citation V, had multiple unaddressed issues with its pressurization and environmental control systems, including an overdue copilot oxygen mask inspection, which prevented oxygen from being available to occupants during the depressurization event.
The unresponsive aircraft prompted NORAD to scramble F-16 fighter jets, which observed the pilot slumped at the controls and unresponsive passengers before the plane eventually spiraled and crashed, killing all four people on board.

The pilot and passengers of a small aircraft that became unresponsive to air traffic control and triggered panic after flying over the U.S. Capitol complex were likely incapacitated by a lack of oxygen, according to a final report released by the National Transportation Safety Board this week.

The oxygen problem was caused by a loss of cabin pressure during the flight, the NTSB said. The aircraft, an 11-seat Cessna 560 Citation V, had a number of issues related to its pressurization and environmental control systems, including a copilot oxygen mask overdue for inspection, and there is no indication those problems were addressed before its final flight and crash, which killed all four people on board.
