OSHKOSH, Wis. — To rise off the ground wearing a jetpack is to feel the force of dreams. Very, very noisy dreams.
On Tuesday, an inventor from New Zealand unveiled what he calls “the world’s first practical jetpack” at the EAA AirVenture, the gigantic annual air show here. The inventor, Glenn Martin, 48, who has spent 27 years developing the devices, said he hoped to begin selling them next year for $100,000 apiece.
