"The Final Countdown", there's a brief glimpse of the slip string on an F14 Tomcat which always makes me smile.
Let's not imagine what'd the aerodynamic forces do on jet fighter if flying badly uncoordinated.
I recall (from my meagre experience, PPLH training not so long ago) bashing circuits in R22 in SVFR weather with some drizzle - less RT chatter from FW VFR training, that I found it bit hard to take off, speeding up and climbing, while the wet strings stuck to window slowly bothered to work about 50-60kts. Unfortunately, no ball to look at. Flying gliders, I prefer string, keeping eyes out (although there isn't any ball usually anyway).
Shawn's book is nice. Have to start reading it up for part-66 mod 12 which I'd like to pass over next year or two.
