Welcome to the forum Tim !
I think considering the amount of time you re doing a brilliant job!
I used 2 tabs on a (safari) browser where I keep both the live track and this thread open all the time.
The scroll box is a big improvement.
Perhaps for the return leg you can get agreement from the pilot to post more info in the scroll box as and when it comes available. Things I am thinking about are:
weather updates en route (you may be able to link to an aviation weather site for it
Pilot state as and when he reports in (tiredness etc)
updates on ETA for the next fuel stop
State of the plane and engine
Finally unless your wife has collapsed would it not be great to have a tab on the website where people (who have registered) can post their comments directly, or failing that make a link on the live route page to this thread so that people can also read what is being posted here?
Regards from Tulip country!
