The Vulcan has already left Leuchars today (Sunday). Decision to go early seems to have been weather related.
If that's correct, then what was making all the noise over my office (in Kinross) around 11.10 today? Haven't heard that much noise from an aircraft in years so I assumed it was XH558 - mind you, it's not much of a VFR day today so maybe it was something more modern (and less exciting)
