I've told it before, but I'll tell it again.
Mid 80's , Location between Corris and Dolgellau, Mid Wales in the Talyllyn Pass (A487) and I was sat on a motorcycle at traffic lights facing up the valley on the road which hugs the side of the valley. For those of you in the know this is part of the Mach loop and is a flowed valley.
Through the gap at the top of the valley came an F4 on its wing tip and LOW. Levelled out and came towards me.
For some silly reason I flashed my headlight at the rapidly approaching toom.
It went past me about 40 feet away, 100' above the valley bottom, fully loaded for bear.
And sat in the back was the nav giving me the "V"s with white gloved fingers.
I will never forget that........MAGIC!!!
