That's two planes. I haven't been to the meetings for a few years.
It was a small fleet of aircraft, in fact. But the point is that it was the [i]same[i/] fleet of aircraft, the Duchesses and Sierra, that FFF flies, about which you said:

Overall, I'm not disputing your point. Obtaining PRNAV approval is pointlessly, and therefore dangerously, difficult.
