All male talk

Yesterday I went to a talk about the development of airwings. Interesting talk, but the remarkable thing is that there were about 30 men, and not a single woman! How the hell is that possible. OK, I expect the number of women at such a talk to be considerably lower than at a Robbie Williams concert, but not zero women. I know for a fact that there usually are women at hackers conventions. So why none at this talk? Very strange.

Anyway, the talk was very interesting. It turns out that it is practically impossible to fly faster than about 90% of the speed of sound, because at that point the air resistance increases very fast. Planes that go faster, use up a lot more fuel, like military planes and the Concorde (that's why it was so expensive).
