Definitely no spin training on the Gnat - intentional spinning was strictly verboten
No spin training done on the Hawk at the TWU although I believe that spin training was done on the Hawk by 4FTS at Valley prior to students coming to the TWU. It was almost impossible to spin the Hawk accidentally as, the moment it departed, letting go of the controls effected an immediate recovery and you could immediately get back to the business of trying to shoot down your opponent. (what else would you be doing to go incipient?)
