What a beast Colin - well snapped,.. as a youngster we were playing in woods at 'Rivelin dams'... we had a weekend hut there.. suddenly we heard this unearthly howl.. absolutely terrified, we rushed out into a clearing - and peering upwards we saw one of these things..could virtually smell the fumes.. I would guess at a mere 4.000 feet !!.. it then carried on over the treetops and out of sight,.. real scary - and I'll never forget the event./ Cheers from Dj.

An amazing sight and I’m sure
