Core Event
On August 25, Delta Air Lines Flight 437, a Boeing 757-200 (registration N707TW) operating from Los Angeles International Airport to Boston Logan International Airport, declared a medical emergency when the captain reported he was ill. The aircraft landed on Runway 22L at 5:38 p.m. local time, the captain was taken to a hospital, and a replacement crew completed the flight to Boston, arriving around 9:04 p.m.
Background & Context
Commercial flights must have at least two qualified pilots. If one pilot becomes incapacitated, the other pilot is trained to assume full control. Pilots hold a medical certificate issued by an aviation medical examiner, typically valid for 6–12 months. Delta’s standard procedure for crew illness involves notifying controllers, diverting to the nearest suitable airport, and providing medical assistance.
