2 craft stationary in the sky...unmoving for 1 hour.

Went outside and saw 2 craft with bright lights on them. They never moved. We kept going outside over the course of an hour and they never moved and stayed stationary low in the sky. After 1 hour we went back outside and they were gone. While they were stationary in the sky, we never saw another airplane in the sky...which is unusual. After they left, we started seeing airplanes flying in the night sky as usual.
