From memory...
The engineering company that designed and built the bridge was 100% female.
By definition inexpert at maintaining an erection.
No, it wasn't. The CEO is a woman, but the engineer who signed off on the design, Denny Pate, was a 61 year old white male, who presumably should have had enough experience to see the risk.
Lots of good discussion on engineering forum where I got the above organizational chart.
