On the evening of Sunday, April 26th, Montgomery County fire and rescue units were dispatched to the Potomac River at Pennyfield Lock to rescue a person reported to be in distress in the river. The standard protocol for this type of rescue calls for the Park Police to also send a helicopter. Eagle 1, manned by pilot/sergeant Kevin Chittick and rescue technician/paramedic sergeant Chris Perkins responded. When Eagle 1 arrived, the crew spotted a man whoâd apparently been swept about a quarter mile downriver by a swift current and had managed to swim to an island. Since there was no access from the shore, Perkins jumped about five feet from the helicopter while Chittick maintained a hover. Perkins evaluated the manâs condition and found that he was not seriously injured. A Montgomery County fire department boat picked the man up and brought him to shore. The man declined further treatment and transport to a hospital for treatment of a leg injury.
