Message: Whilst having a cigarette on the balcony I looked up to see two lights in the sky about 100m apart heading West.

Just assuming they were planes, I didn't think much of it - that is until the second one stopped going West and suddenly zipped off in the opposite direction at high speed.

Within about 30 seconds, the other one had practically slowed down to a standstill, before going off in the opposite direction for a couple of seconds and then ZOOMING off to the West again (and out of sight).

To my knowledge there are no human-built crafts capable of performing such feats.
