Submission + - Dad Builds 700 pound Cannon for Son's Birthday 1

Hugh Pickens writes: "The Charleston Daily Mail reports that machinist Mike Daugherty built his son a working cannon for his birthday — not a model — a real working cannon. "It looks like something right out of the battle at Gettysburg," says Daugherty. The 700 pound cast iron and steel howitzer, designed to use comparatively small explosive charges to propel projectiles at relatively high trajectories with a steep angle of descent, has a 4-inch gun barrel that is 36 inches long mounted on a wooden gun carriage with two 36- inch diameter wheels and took Daugherty about two weeks to build at a cost of about $6,000. "I've always been interested in the Civil War and cannons, so I thought it would be a good gift," says Daugherty's 11-year old son Logan. Daugherty said he is not worried about the federal government coming to get his son's cannon because he spoke to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and found it is legal to own such a cannon because it does not use a firing pin and is muzzle loaded so the government does not consider the weapon a threat. Two days after the family celebrated Logan's 11th birthday, father and son offered a field demonstration of the new cannon on top of a grassy hill overlooking Fairmont, West Virginia and on the third try, the blank inside the barrel went boom and a canon was born. For a followup they popped a golf ball into the gun barrel, lit the fuse, and watched the golf ball split the sky and land about 600 yards away. "Any rebels charging up this hill would be in trouble with a cannon like this at the top," Logan says."

Who needs Radar? :) It is kind of cool to see stereo imaging still being used and in far away places. It reminds me of when my dad took me to his work when I was a young teen. He worked for DMAC and took stereo images from Key Hole satellites (KH-11 I think) and using ancient technology hand traced topographical data to be input into the terrain following radar for the F-111 Aardvark bomber. If he didn't use his stereo glasses in conjunction with his little clear ruler device and cartography equipment he could miscalculate the height of a mountain and cause a bomber to by the farm. Talk about a pucker factor! You wouldn't believe the size of the photo enlargers for the stock KH film. They could take that stock (50mm I think) film and blow it up to the size of a wall! I will never forget those trips to his office!

Submission + - NASA can't pay for killer asteroid hunt

CGISecurity.com writes: "NASA officials say the space agency is capable of finding nearly all the asteroids that might pose a devastating hit to Earth, but there isn't enough money to pay for the task so it won't get done. "We know what to do, we just don't have the money," said Simon "Pete" Worden, director of NASA's Ames Research Center.""
