Pilot, passenger rescued from plane that crashed into power lines in Montgomery Co. - WTOP

Two people who were inside a small plane that crashed into power lines in Montgomery County, Maryland, Sunday evening are being treated for serious injuries Monday morning as the investigation into the collision continues.

The pilot and his passenger were suspended inside the tangled plane for hours after it crashed in Montgomery Village around 5:30 p.m., authorities said.

The crash caused widespread power outages across Montgomery County.

Before 1 a.m., emergency personnel safely brought the two people trapped inside the dangling plane to the ground, Montgomery County Fire Chief Scott Goldstein said in a news briefing.

Responders took the two plane occupants to a trauma center with serious injuries, Goldstein said.

The Federal Aviation Administration reported that the plane departed the Westchester County Airport in White Plains, New York, on its way to Montgomery County Airpark in Gaithersburg.

Goshen Road, near the power lines the plane hit, will be closed “for some time” Goldstein said, as authorities still need to disentangle the plane and restring power lines.

The energy company finished the process about six hours after the plane crashed, according to Goldstein.

Around midnight, fire personnel secured the plane and shortly thereafter brought the plane’s occupants to the ground, Goldstein said.

Power outages as a result of the crash impacted tens of thousands of customers in Montgomery County.
