A member of BayLUG (http://www.baylug.org), Justin, created a red aircar a
few years ago, and brought it to a recent BayLUG Space meeting.  I really
liked the "suicide doors" and use of minifig seats for air scoops, but his
was built before many of the newer curved LEGO pieces were available.  I
built a new aircar inspired by his but using more of these new pieces.

details.
