<div class="legacy-text">In 1969, upon their return from the Moon, the crewmen of Apollo 11 were quarantined in the Mobile Quarantine Facility, a modified airtight Airstream trailer, until it could be determined that there was little likelihood of their having brought back lunar pathogens with them. For decades, NASA has used a fleet of Airstream motorhomes to transport astronauts to the launch pad. The space shuttle program used a modified 1983 Airstream Excella beginning in 1984 dubbed the Astrovan.</div>
