I have looked up into the sky over the last three days and what have I seen...nothing! Thanks to Iceland's volcano, I think it is the first time in my life that I have seen a vapour trail free sky. The beautiful blue skys we have had over the last few days are usually marred by all the aircraft criss crossing the UK. Don't get me wrong, I do feel for all those poor people stranded at airports and those who can't get away on their holiday and those who can't get home, but to look up into a sky that is only populated by birds and insects is a rare treat. It is spookily quiet up there.
