We’ve been promised jetpacks since the 1950s and dreaming about them even longer. Just hang on a couple more years.
Plenty of time to save the $150,000 it will cost to buy the Martin Jetpack, which promises to be the first practical jetpack ready for vertical liftoff.
The Martin Aircraft Company has been conducting research and development on personal jet packs for a couple of decades. Even before it became a privately funded company, its founder Glenn Martin had been tinkering with the idea of something that can fly longer than 30 seconds since the early 1980s.

But which company is continuing to innovate in 2015? Is it Apple, with its fitness-focused Apple Watch, Apple Pay, and a new streaming service that hopes to save the music industry? Or is it Google, with Google Glass, self-driving cars, and secret robots?
