I don't understand why there isn't a special register (controlled by the RAF or whatever) that has to be logged every time something unusual is sent into the sky (like weather balloons or when new aircraft are being tested), at least all the government controlled events anyway. There can't be that many such events happening and this way a lot of reports could be eliminated immediately with reference to the register. The next step would be to get foreign governments to co-operate, or at least avoid secrecy about aircraft tests/space missions etc where it isn't necessary.
