What does "warm up all available planes for a break in the weather."
There's a storm, but as soon as the weather is better, the planes will take off? Or it means that they'll take off anyway, right away, even if the weather is bad?
If you are talking about Air Force aircraft, they will be kept ready to fly off even in bad weather (but not while the storm is on; no aircraft will take off in the middle of a storm !). But you can't keep their engine on too long, else they overheat. And as soon as there's a "break in the weather" (une accalmie), they will be off to accomplish their mission.
I didn't want to start a new thread so here I am. I have consulted the Oxford Dictionary and the Merriam-Webster and it seems like "a break in the weather" generally means something different for the British and Americans. It would seem that for Americans it is a change for the better, but for the British it is a change for the worse. Or maybe it doesn't matter as long as it is a change? Could you please confirm?
