Welcome to America, where you are an unwitting tester of many private ventures that have been signed off on by the American government on your behalf.

Remember that complaining about these tests and demanding more control means that you are communist. Unless of course you don't mind waiting around to be harmed by such tests, and are either able to sue, or told that you had no reasonable expectation of safety.
