Because if the airplane didn't have them it wouldn't go. (Long retired round engine pilot.)

BillH is pretty witty!

Dammut. I did it again.

Karl Poppers statement is total BS. It is so stupid only
an " intellectual" could have dreamed up this idiocy.

If someone says " all jews should be gassed," or all " ni^^ers should be lynched," please tell me how any sentient human being can possibly misunderstand these remarks.

Unfortunately, whenever an individual is coined as
an " intellectual" he can say or do anything and many will jump thru their ass conjuring up the " deeper" meaning or the gravitas of that verbiage or deed.

Most " intellectuals" have never, ever held a real job ( for that would be beneath them), and have spent their entire lives trying to prove and demonstrate their superiority over
the " unwashed masses," ocer the throngs of human refuse.
They live in a utopian fantasy world , a " club" of like thinking , self affirming intellectual morons.
