Taking the meaning of private jets to whole new dizzying heights, the Saker S-1 Personal Jet swaps luxury for speed. A whole lot of speed. This military-inspired aerial beast peaks just shy of mach-1, has a range of 1,600 miles and cruises at 45,000 feet. Can be flown by a non-Airforce-trained pilot and even comes with ejector seats. Haven't got a spare seven million bucks just yet? Don't worry, they won't be rolling out until 2019 so there's plenty of time to get saving.
