Despite the US government shutdown, there were some cheesey smiles for American air traffic controllers courtesy of their Canadian counterparts.
Over the weekend, members of the Air Traffic Controller Association from all over Canada had more than 300 pizza delivered to American airports to lift the spirits of air traffic controllers working without pay.
On Friday, officials for the National Air Traffic Controllers Association in the States announced plans to sue to government as the shutdown continues.
So far there's no end in sight.
