Yes, but it wouldn't be the "red" seen in the photos. It would
glow more like a 'blackbody' - think of very hot coals, more
orange than red - as the temperature during reentry gets very

Since the object was first seen 10 minutes before the shadow
boundary, and considering that there is no evidence of the earth
in the photos, an object at lower altitude that was glowing due
to reentry heating would have to be far _ahead_ of the Skylab.

Furthermore, I can't imagine how the astronauts would have
thought it was anything other than a reentry if they saw it
streaking along.

When it hits the ground is not relevant since it stops glowing
brightly long before then. Stops glowing brightly at least by
the time it reaches 8 - 10 miles (more likely 20 miles) because
the fall slows it and cooling increases as the atmosphere gets
