The piece of metal is described as being a few inches long. Abby Baker told NBC Washington that her home is in the flight path for aircraft from Dulles International Airport.
"At first, I thought maybe a gas pipe burst or something, and then I found this piece here that I thought maybe was a pipe from a gas pipe,” Baker said. “But when I had the gas company come out, they identified it as likely a piece of aircraft."
The National Transportation Safety Board will reportedly analyze the object and check with area airlines to see if there are related reports with any planes.
