Dassault
The Dassault Falcon 5X is the first private jet with a skylight.
Debuted in 2013, the plane has room for 16 passengers. It's equipped with new Snecma Silvercrest engines that Dassault says make it more fuel efficient than competitors like Bombardier's Global 5000 (by 35%) and Gulfstream's G450 (by 30%).
The price? $45 million.
That puts it well below the $65 million Gulfstream G650, still the biggest, fastest, and overall best private jet money can buy. But Dassault strikes a blow with a cabin that is actually wider and taller (albeit shorter) than that of the G650.
And, for cool points more than practicality, it even has a skylight!
