Nope., I wasn't replying to his post, I was replying to the original post
from Ron.Didn't make that clear, sorry.

Sorry language barrier again. In English the qualifying statement used above
indicates that I was not sure that this was an applicable analogy. Also NB
that I hang around with guys at work who glide and when they do use a prop
tend to use designs that can glide for 14 miles or so with no engine from
cruising altitude. Handy when flying to France. My reference point, which
biases my view without additional data.

Maybe in your industry not in mine :-) But, if other listers are not
aerospace/military types they won't have this mindset.It's always worth
mentioning again in case someone somewhere thinks up something new isn't it?

Refer back to note on which post I was referring to.
