Cirrus Design Corp.’s newest luxury aircraft (called The-Jet) was such a secret that employees not directly working on the project were allowed to see it only hours before it was unveiled to those who had placed a $100,000 deposit for a personal jet. In addition to cargo space for mountain bikes, camping equipment, golf clubs, and skis, the single-engine jet features a whole-plane emergency parachute. Expected to be flying by next summer, The-Jet has a suggested retail price of “about $1 million.”
