MECHANICSBURG, Pa. (AP) - Authorities say two upstate New York businessmen aboard a helicopter were killed when it crashed in a Pennsylvania backyard.

Authorities in Cumberland County say no one on the ground was injured in the Thursday night crash.

The helicopter's pilot was high-profile Buffalo, New York, developer Mark Croce. His passenger was a former trustee in the western New York suburb where both men lived.

The aircraft was headed to Buffalo from Washington, D.C., when the crash took place near Mechanicsburg, Pennsylvania.

The Federal Aviation Administration and National Transportation Safety Board will investigate.
