Alvin pilot Mark Spear conducts show-and-tell for new crew members as
they sit inside the Alvin submersible, which was housed in its hangar
on the research vessel Atlantis for an evening in December 2006. Spear
and other pilots interview their passengers prior to descent,
explaining procedures and protocol and addressing questions and
concerns. He reassures the claustrophobic and counsels the weak
bladdered with a calm demeanor and authoritative voice.
