And I know that all the holes are countersunk because I was the one who was in charge of drilling all of them....
Us, too... Unfortunately, we engineered things too closely, and while we could climb our practice hump, and the humps at FLR, we could not climb the humps at Championship.

My students learned a bit of a lesson about design tolerance this year!
