You wouldn’t measure yaw by the pitot tubes. I suppose it’s theoretically possible, but it would be complicated and imprecise. Yaw is measured by a gyro (modern planes are a laser ring gyro rather than a spinny gyro). The pitot tubes would all feed into air data computers for various systems. Flight instrumentation would have at least three (redundancy and error checking) and the fourth could possibly be for weapons systems or something similar, not sure.

That is definitely not the Hunley. It’s a similar size, but a very different design.

I’m sure a lot of sex workers make money while pooping.

What is Jeff?
