I can attest an F4E can take off on one engine - one of our alert
birds did it at Bitburg around 1974 or so. Scrambled off Zulu alert,
simultaneous cartridge starts, one engine didn't catch, crew didn't
catch that, about 6000 feet down the runway and still on the ground
the nose gunner wised up and punched off the drops and "single-ugly'
left the ground to return to 'double-ugly' after an air start. Crew
got a Delta Sierra award. Fire trucks got to wash the JP4 off the
runway. That incident caused the cessation of simultaneous cartridge
starts - too bad; they were always kind of neat on hot scrambles.
Nothing like 'Instant go' to get the adrenaline pumping.
