Groen Bros. Aviation in quest to build a jet-fast heliplane. Looking to go vertical

Sitting in his office with a picture of an obscure 1950s flying machine on the wall, Groen Bros. Aviation http://www.groenbros.com/index.php President David Groen recited the company’s latest mission – design a rotor-type aircraft capable of vertical takeoffs and landings that can fly 400 mph.

The aircraft, which has been dubbed a heliplane, also must be able to carry a 1,000-pound payload for 1,000 miles before refueling.
