If it is a balloon flight, then I don't think any ATV'ers will
mind just staying on 144.34, since there has always been synergy
there.  Short duration balloon flights have always been welcome
on the ATV calling channel (though usually they have had ATV
cameras, etc)...

Otherwise, though, there is nothing wrong with your sugggestion,
and I would have no objection...

Sounds ok to me.
