Flashing swarm of objectsWe didn't know who to report this too I highly doubt anyone that didn't witness it would believe it anyway.My husband and I don't believe in aliens but we ran out of logical reasons for what we witnessed last night.We're on holiday in Portugal and my husband called me outside last night quickly because he'd seen something. He pointed up to the sky and immediately I saw what he was talking about.It looked like what I could only describe as at least 100 'stars' all moving the in same direction across the sky, about the speed of a plane. They all flashed on and off in regular intervals but individually. So they didn't all flash at the same time but they were all flashing.We saw them move across the night sky until it was too far away to see them any more.I tried to video it but it didn't show up on my phone camera.
