An experienced Oregon pilot who mentored countless others, a 22-year-old flight instructor from Texas and a student pilot from the United Kingdom were killed when their two helicopters collided in Oregon.

Three people were killed when two helicopters collided in midair near an Oregon airport Thursday, leaving federal investigators working to determine what caused the crash.

Law enforcement and rescue personnel arrived on scene to find the wreckage of a 1995 Robinson R22 and a 2018 Airbus AS350 B3 in a field adjacent to the highway.
