NASA officials expressed a great deal of concern over the descent of Skylab, a satellite
which was slowly making its way back to Earth and was expected to reenter our
atmosphere within the two weeks. The aluminum Skylab was not expected to burn up on
reentry. In fact, it was feared that some 400 to 500 pieces, some weighing up to 1,000
pounds, could survive reentry. These pieces would not all land in one area, but would be
spread over hundreds of miles causing a great deal of damage to property and endangering
human lives. At this point, we just don't know where or when it will come down or how
much damage it might cause.
