I already did.

I guess there are still a couple of people out there that believe the
aircraft won't take off.


Add a pinch of gadfly and stir until frothy......... d:-)

I have my seat belt and shoulder harness tightened, and I will try not to
make any sound.

Laughing is allowed...

I would be interested in knowing which airport that is. I know that they
have used Alameda and Hamilton in the past. Which airport are you referring
to?

Quoted from the Discovery channel
schedule:http://dsc.discovery.com/tv-schedule...=1.13056.24704....

(My local paper's weekly TV schedule has just the brief summary "Landing
a
747" so I presume the plane they attempt to land without training is a
747.
Will be interesting to see if they try the real thing and are not limited
to a simulator.)

I'm really anxious to see this episode, because apparently they filmed
the treadmill myth at my home airport.

Better clean it up before Mom sees it.

A friend of mine was absolutely convinced that if you are flying into a
strong headwind close to stall speed and make a U-turn, you will stall
(because now the wind is coming "from behind").

The basics of flight just isn't obvious to some people.


Ah, but if you are flying near stall with the wind, and the wind suddenly
slows, will you stall?
..OR.
If you are slow on approach, into a gusty head wind, and a gust suddenly
resides, will you stall?

Partially so. IF you could do a 180 degree turn super fast, like .1
second, you would stall.

At least for the amount of time it takes the airplane to accelerate, the
wind would be making you go too slow.

Of course, no plane can make a 180 degree turn that fast, so we are all safe
from the dreaded downwind turn. g

I think one thing that people don't realize is that while a car can make an
instant turn, an airplane can not.

Well, all but Shawn Tucker's plane. I think he could make the turn in less
time than .1 second, from the crazy crap I have seen him do!

Yes -- Your momentum needs to catch up with your new (reduced) airspeed.

.OR.
If you are slow on approach, into a gusty head wind, and a gust suddenly
resides, will you stall?

It depends on how much margin you have between stall and airspeed to
begin with. If the margin is less than the (now non-existent) gust, you
will stall. Otherwise, you will see a sudden increase in sink rate.

Yes, and they aren't obvious to others just as proper use of grammar
isn't obvious! :-)
