The pilot of Flight LA505 flying from Miami, Fla., to Santiago, Chile, died Sunday mid-flight, forcing the plane to make an emergency landing and leaving hundreds of passengers stranded in Panama.

The incident happened three hours into the trip after Captain Ivan Andaur began feeling sick at a cruising altitude of 37,000ft and left the cockpit of the LATAM Boeing 787 Dreamliner to use the lavatory where he later collapsed.
