If you fly over London then Paris, is 30,000 feet above sea level any different over Lindon than Paris? If 30,000 feet is maintained between the two
cities, why would there be any vertical speed indication on the VSI? In either model?
I've already explained this...
Do you know what the VSI is used for on planes? It measures for ascent, descent, and level flight, in air, using air pressure around the plane during
flight.
When a plane lifts off, the VSI measures it as an ascent. The altimeter measures it as altitude, which starts at 0 feet, or sea level, on the ground,
and when the plane lifts off, the altitude goes higher and higher, as it ascends.
After the plane reaches cruising altitude, say 30,000 feet, they stop the ascent, and the VSI measures it as 0 fpm, or level flight, while the
altitude is steady at 30,000 feet.
If the Earth was curved, a plane would have to FLY in a curved path, to stay at altitude, obviously.
You simply say 'if the plane flies 30,000 feet over both cities, why would the VSI measure anything different for either a curved surface, or a flat
surface?' Because over a curved surface, to stay at 30,000 feet, the plane would have to DESCEND throughout the flight, to stay at 30,000 feet
altitude, that's the crucial difference in a plane flying over a flat surface, which is the case, obviously.
It's impossible to fly over both surfaces at altitude the same way, therefore.

Shortwave radio
en.m.wikipedia.org...
Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere.
Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave
or "skip" propagation. Thus shortwave radio can be used for very long distance communication, in contrast to radio waves of higher frequency which
travel in straight lines (line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave radio is used for
broadcasting of voice and music to shortwave listeners over very large areas; sometimes entire continents or beyond. It is also used for military
over-the-horizon radar, diplomatic communication, and two-way international communication by amateur radio enthusiasts for hobby, educational and
emergency purposes, as well as for long-distance aviation and marine communications.
If the earth is flat. Why is there a different reception range for shortwave radio vs FM?
You think shortwaves have the exact same range as FM waves, then? Is that your argument here?
So what are you trying to argue here, since I have no idea, other than the above...
All waves on Earth, whether FM, AM, shortwave, microwave, or any other wave, which exists on Earth, they cannot 'bounce' off something they invented,
as our 'ionosphere', a zone of Earth's atmosphere so distant, so high above Earth, that nobody can ever prove it exists, except for those who claim it
exists, not a shred of proof it exists, and nobody can ever confirm their claim is true, or false, which is the whole point of claiming things nobody
can ever prove, or test, or observe at all.
They have so many worthless claims, just like claiming an 'ionosphere' is air, but not the same air, yet is there, but so far above Earth, nobody
knows about it, on Earth, except for the 'scientists', who have supremely powerful instruments, which nobody else has, or ever will have, either!
Saying we now have an instrument, based on radar technology, yet sees objects that are 'over the horizon', out of our view, nobody can see them, or
detect them, before now....
What does 'over the horizon' mean, to those who termed an instrument 'OTH' radar?
We can already see some objects that are/were 'over the horizon', by using magnification, so what is 'OTH' supposed to mean, exactly? Seeing objects
that are beyond the horizon, once meant objects out of our view, by eyesight. After it was still in view, simply using magnification, they said it
wasn't claimed at all, only assumed to be their claim, which lasted for over 400 years, and often used today, but it is meant differently now, sort
of...
They claim this instrument does, or can do, is exactly what they've claimed about shortwave - 'bounces' it's signals off the 'ionosphere', back to
Earth!
It's just a different version of it, now.
Except they never said shortwave radios were/are 'OTH' instruments!
Shortwave signals are simply different than FM waves, which are different than AM waves, as we all know. They each have different frequencies, and
emit different types of EM waves through the air, and they have different ranges.
The shortwave signals were a problem for ball-planet claims, however. Because shortwave signals prove Earth IS a flat surface, when it is capable of
receiving radio signals from thousands of miles away, which cannot happen if Earth was a ball. The signals would never span over long distances, if
Earth was actually a sphere.
That's why they had to make up something to excuse the truth, like they always have, and will always do in future... over and over again.
They suggest Earth's atmosphere is not only air, which varies in oxygen levels, from sea level, to higher altitudes, lesser the oxygen levels found...
But that's a well proven fact, obviously.
And we already know that the air, at any levels above Earth, do NOT 'bounce' signals back to Earth, when we point them upward!
So they invented 'layers' of air, called it the 'atmosphere', and one of the layers - called the 'ionosphere' - will conveniently have the ability to
'bounce' certain signals back to Earth.... who figured?!?
There is no proof, no valid evidence, for an 'ionosphere' even
existing above the Earth, let alone being some sort of 'bouncing' layer, to
boot!!
They've lied from day one, and have lied ever since, without fail.
We can easily tell if a claim is legitimate, or at least may be legitimate, from any claims which are purely made up, faked, invented....
But one must look honestly at those claims, first of all.
When they claim rockets fly up into 'orbit', for over 50 years, how does anyone believe the first 3-4 minutes would ever prove their claim is true?
There is nothing to prove their claim at all.
If I claimed to have a flying car, but told you where to see the car speed away on a highway, for the first 3-4 minutes, as it goes out of sight,
would you believe me? What if I later showed you a few clips of my car, flying in air? Would you believe me after that?
The simple fact is without any valid evidence of a flying car, nobody would ever believe my claim is true, unless it is actually seen by everyone,
filmed by people who are present to witness all of it, shot from various angles, too.
After all, you'd be able to see my flying car, when it actually goes from the ground, and fly in air, which proves my claim is true, without any
doubts, because all of you saw it, and filmed it, in person, at the scene..
If I don't tell you where to see my car as it actually begins to fly up into the air, when I have no reason for NOT telling you where to see my car
fly into air, there is no way you'd believe my claim. NASA's claim is even worse
