Just 10 minustes ago I saw a big 4-engine plane flying out of Lisbon, it was mostly in clouds so I couldn't see it well. What I did see was that it wasn't a 340 (as it climbed much faster than they do, and looked different), and it certainly wasn't a 747 either.
It seemed to have the Airbus livery, white with blue tail, blue continuing on rear fuselage.
Did I just see an A380? Or an Il-96 perhaps?
