All three of these servers, however, provide NS responses:

www.airfrance.fr.	87600	IN	NS	ns2isp2.airfrance.fr.
www.airfrance.fr.	87600	IN	NS	ns2isp1.airfrance.fr.

That's not right... all three of the servers are "lame" (as you noted
from your logfile).

airfrance.fr needs to fix their delegations.
