I agree, log the information as soon as it's available.

Yes, I think that makes sense. In this file we could/should save
pilot, plane, takeoff/landing times and maybe the filename of the
corresponding IGC file and/or event file!?

One file per flight with all useful events. This might even match
http://www.xcsoar.org/trac/ticket/1455
We could also think about using the IGC file for this as there is a
line specification for "events".
