Any clues?
 

I wondered if anybody could identify the aircraft I saw recently.
I live in SW Shropshire, UK, and saw a very unusual military aircraft pass overhead. I can only describe it as "triangular", it was flying at around 5000', relatively slowly and quiet. It looked rather sinister in a way, like it should have been at 50,000'+ spying on something!

Thank you, I'm pretty sure that was what I saw.

Seems likely!
