"Ah, I love the smell of Avpin in the morning!" (Robert Duvall, Apocalypse Now)
Nothing quite like the streaming eyes and burning throat to cure the hangover (ok so maybe it was the 100% O2 that did the trick)
The Lightnings in Cape Town all retained the Avpin starting system. IIRC the owner managed to secure a fresh producer of the stuff. It is not that different in make-up to the hydrazine used in F-16 emergency power units.
FRADU: I know(!) when XF516 crashed it was indeed avpin started, but it was poured in from a container rather than being a cartridge.
The electric start option for the Hunter involves a tray of batteries and the engine spins up quite slowly.
Typhoon DA2 has a hydrazine power unit which is for the high risk trials, but such is the HSE environment that the unions negotiated extra payments for the folks handling it.
