A pilot proved his skills by landing his powered hang glider in a
residential area after the propeller fell off during flight.

It fell from the air and crashed into a house near Chippenham. Nobody was hurt.

The pilot, described as having "nerves of steel" kept his cool as the propeller
fell off, and he glided safely to the ground behind a housing estate.
