Drewet 1909 glider

Oliver H. Drewet (or Drewett, but definitely not Drewer) returned to Asansol, India to work as an engineer. It was there that he built his glider, based on a model that he had built before moving to India. A test flight, claimed to be the first in India, was made on 1 March 1909, down an inclined railway, on top of a truck. After 100 yards the machine left the truck with Drewet on board, and flew a distance of 20 yards before crashing.

Dream Wings Valkyrie

The Valkyrie was a sleek, speedy looking airplane on a computer screen. Dozens of DreamWings depositors made their decision to buy a plane while they were sitting at the controls of the prototype, a happy grin on their face. They had found the perfect plane.

One thing led to another–dreams were crushed, careers were ruined, no planes were ever delivered and in 2001 DreamWings ceased operations forever. When DreamWings closed its doors, it left 145 customers behind – customers who lost nearly $1.5 million in deposit money.
