Review: New book on the U2 super motorglider

Rutan planes are capable of "Tail Diving". *And my favorite, Kirk, is
the dreaded "Cork-screw death spiral"

OK, enough of this silliness. :-) *Let's all buy some books, profile our
wings, and watch the OLC postings of those that are getting to soar!

I tend to associate "tail diving" with what glider pilots hope to do
on Friday nights after getting lucky (!?) in the local bar....

Back to sanding the wings, metaphorically!

Cheers,

Kirk

Thanks; I'll try to remember all this the next time I'm trying to center
a thermal and a pee bottle at the same time.

By definition half of everybody is indeed dumber than average (sense,
median.

Also, by definition, it is likely that more than/less than everybody is
dumber than average (sense: median or mode).

Admittedly, mean is the commonest usage, but not the only one.

We went through this already :-). No! That is the definition of median
-

not average.

Given the (contrived) sample of 1,3,5,7,99, the average is
(1+3+5+7+99)/5 = 23. The median is 5 with half of the sample less, and

half of the sample more. Yeah, off topic, I know.

Is that 400 nautical miles per hour squared?

Reading that is as painful as hearing fingernails on a blackboard...

For me "nose dive" is a real irritant. The blasted plane is just diving
fer chrissakes. They seldom if ever "tail dive".

No, they "tail spin"!!!! *After "looping the loop", of course.

The "tail-spin" occurs as a result of inproper use of the rudder
"peddles" during a "flip".

Interesting, thanks.

Could we perhaps be precise. Average could = mean, median or mode. It
does not always mean "mean". If it's not clear from context, say which.

Now, of course, one could be referencing a statistical distribution
that is symmetrical, say the Uniform or Normal distribution... In
which case, mean=median=mode.

If you're working with sample data from an unknown population
distribution, the distinction is important and often misused and
abused in order to influence others.
