In reply to deepsoup:
I have been struggling to understand the magnitude of this also, some numbers '
BG 66 miles 27,000 feet. x 2, =132 miles 54,000 feet
What have mere mortals got to compare this with?
The 3000;s of wales 1 crossing = 24 miles 12,000 feet
QED.
54,000/ 12000= 4.5 132/ 24= 5.5
So something akin to 5 times the Welsh 3' in a weekend ! and not a lot do it as a Double
Well done nicky
