I found this YouTube video really refreshing and helpful. It’s nice to hear a Brit voice for once and to watch a very simple, straight forward, and to my mind, logical guide to the dreaded nil wind, forward launch.
It’s not the whole story of course but it does address a rarely considered element; the angle of attack. It also tackles the bane of old farts’ (like me) lives; the 200 metre puff and pant dash and the ensuing near heart attack! and how to reduce the inevitability of either or  both happening.

See you Walking In The Air soon, Mitchel N.Mann
