Capt and F/O are both fine, they did not smell anything, nor see any smoke. It was only the CC who informed them about that.
The CC were taken to hospital just to have a check, they are both fine.
There was no smoke onboard, all pax fine.
My thought is some kind of gas (produced of leaked from cargo) that came into the cabin.
Normal landing in NCE. Very well handled- all the crew!!
Happy days
