arrivals spacing
Hello
A couple of weeks ago we were holding at CDG, for a long time (busy afternoon), I assuming waiting for permission to align on the rwy and take off. Many arrivals in sequence during this time. At some point a landing 747 was right over the threshold, while the previous jet (regional ?) could be seen turning left and vacating the runway. I think I saw the 747 land immediately after. How common is this (I mean, it seems a bit close)? Is it possible that I did not see what I think I did? Just curious...
Thank you
