Can anyone verify Spad SIOP missions of 24 hours?

Hope I don't put my foot in my mouth, but IIRC Spad's could be up 6-7 hours
max conserve. Remeber that they did not have air-refuel capability (well,
not exactly, they gave using D-704s, but couldn't get), and more than that
they used so much engine oil that I believe the engine would seize before
they pushed 10!
