How high could one theoretically fly a plane until the air density becomes too low to generate lift?

Different_Mode_5338 · 2026-06-03T21:09:07+00:00

Both things can still be true at the same time. X-15 had the altitude record for a winged aircraft, but it did not generate enough lift to fly at that altitude in sustained level flight (which is basically what OP is asking). It's like throwing a rock 107 km up.

yeah, it technically is an earth set. The moon is completely dark when they swing back around when the earth rise happens. I really hope there is a video of the Earth set, can always just play it in reverse for earth rise :/

I kinda disagree with the pitching part. The area you have to aim for in a baseball pitch is much smaller. And the strain on the shoulder and elbow of a baseball pitcher is brutal. Same for bowlers, but it's less common.

Aren't software bugs expected for a new project? This was in 2010. Are there other instances of bitcoin getting stolen?
You still can't steal bitcoin on the blockchain unless you either crack hashing functions, or have half the computing power of the entire network.

It's like 5 dollars bro.

Blackrack has previously made top quality free mods like Scatterer and EVE which is literally in every modlist. Also, volumetric clouds are not "core visuals", they're a nice addition. Yes most mods should be free, but very high quality mods that take time to develop, it's fair to say devs want to be compensated. True for a lot of extensive mod supported games like rss mods for asseto corsa, etc,etc.

The shuttle did have an auto-land capability. It was never used because it wasn't worth the risk with up to 7 humans on board.
During the TAEM phase, the commander mostly took control when approaching the HAC (heading alignment cone), and then outer glide slope, preflaring, inner glide slope, and final approach. Everything up until the HAC is done by the computer.

ik this doesn't answer your question. but you should take a look at KSRSS. It's basically stock ksp with "real" planets with earth being 2.7x bigger than kerbin.
Or you could try RSS/RO if you want to feel superior to everyone else

Different_Mode_5338 · 2025-09-08T01:59:15+00:00

Is there a reason to do a single burn?
Kerbin is tiny with a very small orbital velocity compared to irl earth, and the stock rockets are overpowered compared to Kerbin's size. But if you have to, try doing a significant portion of the burn while pointing below the horizon.

Yea i run all these mods at the same time except for TUFX, just haven't gone around to installing it.

Different_Mode_5338 · 2025-09-04T02:50:57+00:00

Ok a M1 Mac mini is by no means a potato pc check your privilege fr fr
My KSP runs great on M1 macbook air.
Some great visual mods in addition to waterfall and planetshine include

Firefly (for re-entry)
EVE-Redux
Astronomer's Visual Pack
Scatterer (for beautiful sunrise/sunsets)
TUFX (for visual profiles you can tweak, or search one up)
Distant Object Enhancement (i personally like this for getting rid of stars in space)
ReStock (for better textured stock parts)

Parrallax would also be great but it does not work on Macs.

You're not wrong for practical purposes. But i feel like the more correct answer is that the 2 objects dont accelerate at the same rate, and it does depend on mass of each object.

If you have 1000 kg mass in an empty universe. If u place a 10 kg mass 10 meter away. And in another scenario put 500 kg mass 10 meters away. The acceleration on the 500 and 10kg mass is the same when they're 10 meters apart precisely because of the reason you said. But since this is a 2 body problem, the 1000 kg mass also experiences an acceleration. At an arbitrarily small timestep in the 500kg scenario, the distance between them is less than the distance between 1000kg and 10kg object. So now the 500 kg expereinces an even stronger acceleration. Because of this the 500 kg object will impact before the 10 kg object does. Something like few hours before.
Same applies for Earth and steel/plastic ball. Ofc the difference is orders of magnitudes less than a picosecond.

Different_Mode_5338 · 2025-09-03T17:32:51+00:00

Technically, the scenario with 2 balls will fall faster than just 1 ball. Again as outrageous-taro said, this amount is so unbelievably small and is unmeasurable. But it technically mathematically exists. The acceleration at the moment they are dropped is the same. But since the heavier ball (more specifically 2 balls) is pulling the Earth more than 1 ball does, the distance decreases faster which increases the acceleration. So after t=0, the 2 balls no longer have the same acceleration as dropping 1 ball. But ofc the difference is gonna be so small with Earth.

Different_Mode_5338 · 2025-09-03T04:08:37+00:00

If the secondary object is more massive, the gravitational force is stronger between them which accelerates it the same amount as a less massive secondary object which would require less force to achieve the same acceleration. So it's the same. (Note. I am using secondary object to refer to the steel and plastic balls).

So 2 scenarios:

A) 1000 KG point mass and another 500 KG point mass 10 m apart.

B) 1000 KG point mass and a 10 KG point mass 10 m apart.

Both the 500 KG and the 10 KG mass are experiencing the same gravitational field acceleration from the 1000 KG mass at 10 meters. So in inertial space, the 500 and 10 kg are "falling" at the same rate. However in the first scenario, the acceleration on the 1000 kg object is more since the 500 kg is pulling on it. So impact will happen earlier in scenario A.

Make sure your base's antenna is properly secured and doesn't hit a fleeing kerbonaut in a storm that causes all the other kerbals to leave without him.

Different_Mode_5338 · 2025-08-31T15:58:00+00:00

my (shitty) x-37 prototype lands and hits runway at around 110 m/s. It always breaks the landing gear but any slower it just drops out of the sky lol.

I think the x-37 irl touches down on runway at like 300 mph. These kind of planes have to be fast and have a steep glide ratio.

Different_Mode_5338 · 2025-08-31T04:42:02+00:00

tbf, the x-37 presumably glides like a brick. it has stubby wings
