The wind and wings thing is much more easily demonstrated with models. Into the wind of say 20 or 25 mph. I had a couple planes that would hover quite nicely relative to the ground.but if you turned them with the wind without throttling up they would become uncontrollable and succumb to gravity pretty quickly.its the air over the control surfaces that give it control authority and lift.
same reason a carrier turns into the wind when launching

If the plane is moving at 100 knots in a 100 knot tailwind, how could the wings generate any lift?
I don't know the answers to these things other than what I've experienced sailing. For example, if I'm going dead down wind in a sailboat at 3 knots in a 3 knot wind, then I'm just getting pushed and the sails (foils) are not generating any lift.

Indicated airspeed is not the same as true airspeed. And that’s all I have to say about that.

101, heading for a high of 105. Feels like 111.
April and May are our hottest months. Come Thursday a high of 86. Almost sweater weather.

Are you a pilot also? Or do you fly RC planes?

Finally starting on our new roof tomorrow.
We got some interesting instructions:
1. Remove all art from the walls as the vibration from the work can cause it to fall off.
2. Have to park in the street (which makes some sense).
3. We have to allow the workers to use our bathroom (which is weird as a contract term, but of course we would). The issue will be do we have to leave our house unlocked if we are not there while they are working.
4. Cover stuff in the attic as the removal of shingles and nailing of the new shingles can result in a lot of dirt falling onto stuff.

Chiffon Margarine used to have a jingle, "If you think it's butter, but it's not - it's Chiffon!", which my family immediately made into "If you think it's butter, but it's snot"

Margarine itself is a bad joke. I can't believe we used to eat that carp. :yuck:

I think I had margarine at a friend's house once. Mom and Dad wouldn't have let it in the house.

Sorry, my bathrooms are off limits. I’ll get them a portapotty. Next thing you know they want to take naps in your bed.

Contractors working on my house or commercial property do not typically jack with me when they learn that one of my areas of expertise is construction law.
