Here's a 'job lot' showing the 'Training Aircraft' display. Although perhaps lacking the 'impact' of the 'warbirds', the Tiger Moth, Bucker Jungman (CASA) and Stampe SV4 put on a nice show of formation flying, and some graceful aerobatics, and provided a colourful 'intermission' from the snarl and growl of the fast-flying fighters. I particularly enjoyed the display by the Stampe, as I used to get to fly one occasionally, back in the 1980's.
The Gladiator and P-40 did a couple of fly-pasts in formation, before the 'Gladbag' performed a solo display, showing just how manouverable the last of the RAF's biplane fighters was. A Squadron of Gladiators was operational from Roborough during the Battle, tasked with the defence of naval installations.
