I believe everything is in place for a decent balloon model it just needs someone to hook in the horizontal forces < wind > details for doing this @ http://seneca.me.umn.edu/pipermail/flightgear-devel/2002-January/002677.html Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
