This is in contrast to winch launch where the runway is always available.

Is that ALWAYS true Bill? I have never been on a winch though have
quite a few car tows including reverse pully of various arrangments
and I was under the impression that there may be situations where
landing ahead is out though you are to low and/or slow to turn back
safely. I think I learned about his in Piggotts book actually which
was quite an eye opener after my classic American "hook up and floor
it what can go wrong" car tow introduction some years ago.
