I used to commute from Rocklin to Yuba City every day, so I saw many U2's coming in on final approach. They hate to stop flying so they have to make a long gradual descent, otherwise they pick up too much speed and won't descend. Did that make sense? I don't think so but you know what I mean.
Makes perfect sense to me. Well, now you know what happens when you put a jet engine on a glider.
