Oh I am sorry I was a bit unclear. In the US 300 Serco controllers moved 4.6 million safe operations last year. I can't provide you with all the facilities we run but if you contact the FAA it is public knowledge and they will tell you it is around 56 on this contract. I know it isn't as interesting as the unfounded claims that Serco would not adhere to safety, but on the other hand it is true.
