Sunrise over east Belfast with vapour trails

On the way to work this morning, it being a crisp frosty morning, I couldn't help but notice a number of vapour trails in the sky. In this photo there must be at least 7 and there were a similar number behind me. Some were fresh and some were starting to disappear but the frightening thing was that I could see 6 planes overhead and they all seemed to be converging on the same point. Perhaps that reddish glow on the horizon wasn't the sun but a conflagration created by those planes arriving at the same point at the same time (c: It looked as if we were being invaded but the really frightening thought is that if you are on a plane then the odds are that there are probably another 5 in the near vicinity - is it any wonder that there are mid-air collisions?
