Yes. It has no starter. (And, btw: Even if it had one, the simple fact
that it starts *now* doesn't mean that it will start *then*.)

I know some or all start in the air by windmilling. Is there a pull
string starter or the ability to hand-prop on the ground?

Your statement about "the simple fact that it starts *now* doesn't mean
that it will start *then*" is unassailable, however the odds may
improve. If it *doesn't* start now would be a good reason to not expect
it to start in the air ;-)
