We believe the pilots who reported this event probably had witnessed space debris returning through the atmosphere.

The objects were round with bright white lights and each had a long trail of white light turning to red with some blue. Air traffic control had nothing on the radar but another aircraft reported that they saw the same thing as we did. The other aircraft was at 39,000 ft and to them the objects seemed to be at that altitude, wehereas to us it seemed to be at our altitude of 28,000 ft. After 1 or 2 minutes the objects suddenly vanished.
