Right, so this happened last November 5th in Lewisham, South London. Me and my girlfriend were watching the local fireworks from our flat balcony with a couple of mates. Cracking display it was, proper impressive.
Around 9:15pm, during a lull between sequences, I noticed this orange orb moving erratically across the sky - not like a balloon or drone, it was snapping between positions. Dead silent too. No sound whatsoever. My mate Dave said it was a weather balloon but honestly mate, I've seen those. This was different.
It hovered for maybe 8 seconds above the park, then just... vanished. Not descended, not moved off - switched off like a light. The three of us all saw it. I'm not one for jumping to conclusions but I'd love to know if anyone else in London spotted anything that night. My girlfriend thinks I'm mad.
