Delta flight DL437, en route from Los Angeles to Boston with 147 passengers, was diverted to Detroit after the pilot reported feeling ill and needing hospitalization. The incident occurred on Tuesday as the Boeing 757 was flying over Michigan.
An air traffic control recording captured the captain's transmission, stating, "This is the captain. I'm the one that's ill. I'm gonna taxi the jet to the gate, and then I need to go to the hospital." Air traffic controllers guided the aircraft to a gate at Detroit Metropolitan Wayne County Airport.
The flight, which had departed from Los Angeles International Airport at 10:45 a.m. PST, landed safely in Detroit. A replacement crew boarded the aircraft to continue the journey to Boston. Passengers arrived at their destination approximately 90 minutes behind schedule.
Delta confirmed the diversion was due to a crew member's illness and issued an apology for the disruption. The airline did not release the pilot's name or provide further details on his condition.
Procedures for a pilot incapacitation or illness involve the co-pilot assuming control of the aircraft while the other crew member communicates with air traffic control to arrange a diversion. This protocol was followed, according to aviation experts.
"In airliners, if you're not flying, you're the one doing the talking because that allows, in this case the first officer, to focus on just flying the airplane," explained former pilot Matthew Buckley. "They did this by the book. If any pilot is incapacitated or feeling incapacitated like, 'Hey man, this is pretty bad,' you need to divert to the nearest suitable airfield."
