NASA officials have named MacDill AFB as an alternate landing
site for future space shuttle missions. Alternate sites are
typically selected based on weather conditions or the power level
of the shuttle during re-entry. Software updates to the
shuttles’ landing programs make it possible to land at more
locations than previously available, said Marty Linde, director of
landing support at Johnson Space Center in Houston.
"The new software, which was scheduled to be installed before the
accident last year, expands the possible landing sites from 25 to
45," said Mr. Linde.
