A propeller sliced through the upstairs Bucks County bedroom of Brian Rush and landed near a crib.

Catherine LaPat was outside on her deck when she heard a plane sputtering overhead. She says she and her daughter ran towards the crash to see if they could help.

"People were yelling at us to get back cause we were running towards it and said that 'it's gonna blow, it's gonna blow,'" said Catherine.

According to the Federal Aviation Administration, the plane departed from Doylestown Airport and was en route to Gunden Airport in Perkasie when it went down right near Pennridge Central Middle School.

No one on the ground was injured.
