After putting 30 years of hard work into completing a prototype jet pack, New Zealand's aerospace manufacturer Martin Aircraft may finally be able to take its baby on a test flight with a human pilot. Earlier this week, the New Zealand Civil Aviation Authority issued an experimental flight permit for development test flying, which would allow a human pilot to fly the aircraft for the first time ever, as opposed to an operator on the ground with a remote control. If all goes well with test flights, Martin Aircraft says that the first consumer-grade jetpack ever, which can float as high as one kilometer and travel at a top speed of 43 miles per hour, could become available for purchase as early as 2015.
