Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

The DG-808 Motorglider - Soaring With The Eagles

DG-808

DG Flugzeugbau GmbH produces what I consider to be the most beautiful flying machines on Earth. This is the DG-808 motorglider, capable of self-launching using a retractable motor behind the pilot. These advanced machines have a glide ratio of 45:1, meaning that for every 1000m of altitude you can glide 45km through perfectly calm air. Of course, the sport of gliding is all about finding thermals and mountain updrafts to enable stunning multi-hour flights. The DG-808 has a maximum speed of 270 km/h, but best performance is at about 110 km/h -- with no engine, remember. People comment that powerless flight must be incredibly quiet, but don't underestimate the roar of air at 100+ km/h.

Soaring is a (relatively) low cost way to get into flying. For more about the sport, contact the Soaring Society of America, Soaring Association of Canada,  or British Gliding Association - they can put you in touch with a club in your region or country just in time to register for a Spring ground school course.
