Seriously, you purchase this converted DC-3 from eBay for $150,000, slap on some new lettering, maybe put a speaker on the roof that makes shuttle sounds when you leave a red light, and sell deliciously-filled thin pancakes out of the back. People will be fighting to give you their money.
As the truck's product page describes:
This kitchen is built inside the only road worthy DC3 Airplane licensed for street use in the world that we know of, painted in the theme of NASA'S Space Shuttle.
This is a once in a life time opportunity to own not only a great money making business, but a piece of American History also. This aircraft was built in 1944 and flew during World War II. It also flew as an airliner during the 50's and 60's and was alleged to have been hijacked to Cuba during that time.
It was converted for street use in 1976, mounted on a GMC Bus frame. We purchased the vehicle in 2001 and converted the empty shell into this completely self-contained commercial kitchen.
It currently resides in sunny Southern California and is now the closest thing to an operational Space Shuttle in the country. [eBay via Boing Boing via DVice]
