The gyrojet pistol (video) - a handgun firing 13mm rocket ammunition, was an attempt to revolutionise gun design in the 1960s. Around a thousand were produced, and some may have seen use in Vietnam. Rifle and carbine versions were also produced. Design problems meant that it never seriously competed conventional firearms, but there is a modern attempt to revive the concept.

Tales of Future Past* — It's been a looong Monday. Do you want to get off the planet and out of the city to a place where you can really live? Well, here's some food for thought on the way home down life's highways. First, take a break from all this depressing war talk. Then empower yourself by giving yourself some space and maybe taking off for a few days. Drive just a bit slower, turn up the volume and imagine that your mechanic will say the tranny's OK after all. Once you're in the front door, take time to get slightly wired and forget all about politics. Get recharged for tomorrow: have a nice long bath, put your mind at ease, watch Ur Fave shOw, and listen to some soothing music. Now, don't things look a lot better?

Maybe they should have let Lance Bass on this one. A Soyuz rocket explodes 29 seconds after takeoff, killing one and injuring eight from the blast. Although it was not carrying any material destined for the International Space Station, launch delays caused by the investigation into the explosion might hurt the IIS project in the long run.

What is Dick Rutan up to now? The reigning master of innovation in aerospace is up to something, as shown in the linked photo. But what is it? Rutan is also helping to bring us rocket powered airplanes and, of course, flew Voyager around the world not so long ago.
