Was there a person at Airbus who was most responsible for the A380 like Joe Sutter was responsible for the 747?

The internet gives conflicting information on this. Do any experts out there or enthusiasts with books on the A380 know the answer to this? Thanks in advance for any useful information.

Would the Lockheed L-500 have been a good airliner?

Would the civil version of the C-5 aircraft have made a good wide body airliner? I realize that with a smaller wing sweep than the Boeing 747 it was probably limited in cruise speed.

Re: YouTube video from 1975 of DC-10 motion flight simulator

I remember an ad in a flying magazine about an airline that for a hefty fee allowed aviation enthusiasts to have 30 minutes in a simulator like the one in the video. I don't remember which airline it was now but it was in Denver if I recall. If I had the money I would have tried it out.
