.....they did! The MK3 Phase III had vipers mounted below Nos1&4. They needed something to get the bl%^dy thing off the ground. IIRC they had to have Crash1 beside them on the piano keys as the Vipers were started. Jet engines running on 115/145 Avgas!!!
Whilst on MK2s at Bky our Sgt co-pilot asked tower for clearance to start our Vipers. It was a dark and rainy night and it took a couple of ticks for tower to catch on; "But you're a MK2!??!"
"Yes but I need my vindscreen vipers", collapse in giggles as capt cuffs him on the side of the bonedome.
No!. I agree the old ones are NOT always the best ones.
