Authorities are investigating Thursday’s fatal crash of a twin-engine seaplane in Perth before thousands of spectators gathered for an Australia Day event. The pilot and passenger on board the Grumman G-73 Mallard were killed about 5 p.m. when the aircraft, captured on witness videos, was seen flying low and banking to the left over the Swan River, then suddenly plunging nose-down into the water.
