1929 Naughtilus Anti Gravity Cruiser
New Zealand has always been a great place to go anti-gravitating. The 1929 Naughtilus Anti Gravity Cruiser is an excellent example of New Zealand engineering, achieving great performance using only a pile of corrugated sheet metal, some wire, and British machinery with unknown workings which, nevertheless, gets the job done. Match, this, NASA. Ha.
The Kiwis have been using anti gravity since the 19th century, thanks to its accidental discovery through Invercargill farmer Gary Wilson in 1863 who, originally intending to construct a slow-cooker for lamb stew inside a shed behind his house, built the first ketone fission device known to southern man. As we now know, the concept never took off commercially because of its inability to cross the equator, where ketone thrust inverts, leading to a sudden reversal of the vehicle's Z-coordinate orientation. An expedition is planned to recover Wilson and his vehicle who, sadly, disappeared in the sea off Japan in 1872 while on world anti gravity tour, accidentally making that other, tragic yet vital, discovery.
