"Aircraft over London, On - no contrails seen
First I witnessed what I thought was a pair of aircraft, one large and one smaller. Following was a second very large aircraft escorted by 3 smaller aircraft. I thought perhaps 2 stealth bombers and stealth fighters but not sure?
There were no contrails. Weather was clear and sunny with only a few clouds. Objects were flying east to west over central London, On at a very high altitude. Appeared white because of altitude."
Our thanks go out to NUFORC for this report.
