Drag - line.
Smujsmith,
I bet Danny can't ! To the best of my recollection, all they told me was that there are two kinds of drag:
Induced drag (incurred in the process of creating lift).
Parasite drag (all the rest).
That's all, folks.
From your Post "Drag Artist" (1918 today), Smuj, it looks as if Halton knew a lot more than my ITW in Newquay ! (which doesn't surprise me).
Danny.
