Mediaeval priests to you too.
What do you think the stall speed is, if it isn't the minimum speed you can fly at while generating sufficient lift?
Above stall speed you can generate more lift by pitching up. At stall speed any attempt to pitch up will cause the loss of flow over the wing, a loss of lift, and a sudden drop in altitude which will make the angle of attack even higher, so the flow separates more...

That link is dead, even when I unmangle it.
They're actually looking into climbing to 30,000 or so (not 55!) then cruising with a gentle climb as they go - as the plane lightens the ideal altitude goes up.

It's not necessarily sudden. You try stalling a 172 or a 150.
which will make the angle
You really need to look at the graph below shit-fer brains.
The stall speed varies with altitude whereas Vne does not. This is called the flight envelope. All aircraft have one, outside of which it won't fly.
That is untrue! There are loads of aircraft where the survival of the pilot is the limit to the envelope not the inability of the craft to fly.
Drivel. It would be pointless to design an aircraft with limits outside which the pilot could not survive.
"The stall speed is constant" "The stall speed varies with altitude"
Make your mind up.

Both are sort of true. Stall speed is constant relative to Indicated airspeed which relies on e.g. the pressure on the pitot tube. However real airspeed varies dramatically for et same 'indicated airspeed', and so too does the real stall speed ..
