SEATTLE (AP) — Passengers who were aboard a Delta Air Lines flight that made an emergency landing on a remote Alaskan island have arrived safely at SeaTac Airport.

Delta spokesman Drake Castaneda says the customers took off on an alternative aircraft from Shemya and arrived in Seattle at about 10 p.m. Monday.

The original flight from Beijing to Seattle carrying 194 passengers was diverted to a military base in Alaska’s Aleutians chain due to a potential engine issue.

Delta sent another aircraft with maintenance technicians, airport customer service agents and a new crew to operate the flight to Seattle to pick up the stranded passengers.
