A top-secret military vehicle launched from the Space Coast Thursday morning.

A SpaceX Falcon 9 rocket launched the X-37B Orbital Test Vehicle from the Kennedy Space Center.

This is the fifth launch of the X-37B.

The launch window was from 9:50 a.m. until 2:55 p.m.

After the launch, SpaceX attempted to land the first stage booster on land, at the Cape Canaveral Air Force Station.

People nearby may have heard a sonic boom when that happened.
