Thanks Terry, it is mesmerising looking at the map!

So where do you think the balloon might turn up, assuming it hasn’t gone down?

I once did a translation from these options to the corresponding flight levels (altitude values) but I've misplaced the envelope somewhere.   There are lot of options on this page, and as a person who has worked with the weather for most of my life and also in my sport, it's a very interesting presentation.  Zoom in /out, drag the earth to any place you want to see -  Fascinating!
