Bad contract writing isn't unique to the Dept Defence. Look at the NSW RTA and their cross city tunnel / epping tunnel / any toll road, and the sale of our airports to ******ports, who sell off anything that looks like it would make more money with a supermarket on it instead of an aeroplane.
But the Seasprite is certainly a flustercluck. Angus, a chopper pilot originally, would understand it better than most. And he isn't the sort to duck and weave.
