What if you could live inside an airplane? Well, one aviation enthusiast has actually made that possible. About four years ago, engineer Toshikazu Tsukii (or Ski as he is commonly known) took on the enormous project of building a guesthouse using parts of retired Boeing 707, 727, 737, 747 jets and military airplanes. Living in Arizona, he found a Boeing 707 fuselage at one of the boneyards near Davis-Monthan Air Force Base. Most of the parts he purchased were ready to be scrapped for recycling purposes.
