Backyard Rocketeers Keep the Solid Fuel Burning
Jamie Clay points out a New York Times article about one sticky wicket faced by
members of the Tripoli Rocketry Association, whose members are some of the private citizens trying to bust into the space-launch business (or just having fun) by financing and building their own rockets.
An excerpt: "On Tuesday, lawyers representing Tripoli and the National Association of Rocketry and officials of the firearms bureau will head to Federal District Court in Washington to resolve the seven-year-old dispute over the hobbyists' use of a flammable propellant, ammonium perchlorate composite, or APCP. The chemical is the main ingredient on the space shuttle's solid rocket boosters. ... The firearms bureau classifies APCP as an explosive and, amid post-Sept. 11 security concerns, requires that anyone who uses more than two ounces of propellant undergo federal background checks."
Most of the people I know gave up at this point, or built small storage sheds that were up to code just to house their fuel which technically, according to the FBI, is not explosive anyway. (it burns rapidly, but does not explode, there IS a big difference actually)
For those not familiar with the term "sticky wicket", it is a cricketing term referring to the state of the cricket pitch. A sticky wicket is typically one that contains too much surface moisture, and can cause the ball to deviate unpredictably as it bounces in front of the batsman. A cricket ball is similar in size and mass to a baseball, and can be bowled at a batsman's body (or head :). Batting on a sticky wicket is a lot less fun than bowling (pitching) on it!
These ridiculous restrictions on chemicals sounds familiar, I've run into the same thing in my trade, photographic printing.
I work in antique photochemistry processes, and the chemicals I've used are now subject to regulation by the Department of Homeland Security and the Drug Enforcement Agency. Just last month, I was checking prices at the same supplier I've used for 30 years, and to reorder the same old chemicals, now I have to file DHS forms with the vendor, including a copy of my photo ID, the location where I will store the chemicals, a detailed description of the chemical formula I use, and a waiver allowing the DHS and DEA to inspect the records at will. I phoned the supplier and asked about these forms, and they said, "oh don't worry about it, we've only had DHS inspect the records 2 or 3 times." Oh I feel so much better after hearing that.
So now I know why the processes I use have almost completely disappeared in the last few years. Nobody wants to subject themselves to scrutiny by the DHS just to make a few prints. The really stupid thing about this is, the chemicals on the restricted list aren't really the most dangerous ones, you can buy stuff from the same supplier that's way more hazardous without filing any paperwork.
