Have you had a little too much Holiday Cheer?
IIRC 99.99% no defects. As long as you don't count emptying out an airport, Shoe Carnival, losing "test" bombs, etc. as defects I guess its possible.
I also think that Management needs to think they need improvement, unlike the TSA who thinks problems are the result of the customer.
PS: Great idea! If only they would, maybe they could improve.
