Hi Culio.
Hope your D of E expedition went well.
Unlike some rather bitter and twisted sounding folks, I'm glad you were given a good view of this Tornado, and hope it lifted your spirits long enough to give you a bit more energy for walking for a while.
In my military career, I went on to often be running distances similar to your entire D of E expedition in one go, BUT I could always find time to stop if anything military flew over. Even now, it brightens my day if I see a Tornado (rare) or Apache/Lynx while out walking.
