Does it have the reentry effect when you go fast enough in real life??

[The Spac]

So, say you go fast (1000+m/s in ksp), and it's basically reentry but not going down. Is it like that in real life? Or is it just because that's what KSP considers reentry speeds

[GoatRider]

If you go fast enough IRL, your plane will heat up. The SR-71, for example, had gaps in the fuselage fuel tanks, and fuel would leak out until it got up to speed and closed up the gaps.

However, your plane can actually burn up and be destroyed. The SR-71 was made of special heat resistant materials that prevented this, but the average aircraft isn't made of that and will just turn into a fireworks show

Right, but I'm not particularly worried about my Cessna 172 hitting Mach 3.2

Fastest I've gone is maybe 180 in a Decathlon diving before a loop.

You dont even have to go all that fast to heat up. The exterior of the Concorde(which only went to about mach 2-2.5? as opposed to Spacecraft which get up to at least around mach 20) actually got up to about 120 degrees Fahrenheit if I remember right. They had to make a a paint specifically for the Concorde so it would stay white. Scott Manley also did a video on heat shields:

Of course! Air resistance will heat up your plane. Just like @GoatRider said, the SR-71 was actually designed with this in mind.

It would heat up your plane, but you wouldn't get much visible plasma around.

As this isn't about the game, it's moved to S&S.

Indeed, heating still occurs IRL, but you would have to be going much faster than in KSP to see plasma. Not typical for a hypersonic plane, but common on reentering orbital spacecraft.

This, 3600 km/h is SR-71 speed, its also the speed of stuff like artillery shells, falcon 9 first stage is up to twice as fast but it need an braking burn to not overheat. 
As I understand superheavy or the BFR first stage is planned to not need an braking burn as its can handle higher temperatures. 

Still leaves the issue with engine parts and other stuff in the back and guess they use braking burn in the start. 

Don't think you get plasma, it also depend on air density, one ABM rocket got it during accent as it accelerated so fast after launch. 
---
KSP increase the heating and effects because the low orbital speed. This is an issue as it makes aerobraking other places than Duna challenging, if you come in with an ship 2km/s faster than orbital speed it simply explodes as its almost double the orbital speed and your speed grows because of gravity in low orbit Duna low gravity makes this works there, doing this on Eve or Laythe don't work well. 

Love how the rear heatshields fold back, main issue was aerodynamic stability.

The Sprint ABM :

Quote

The Sprint was a two-stage, solid-fuel anti-ballistic missile (ABM), armed with a W66 enhanced radiation thermonuclear warhead. It was designed to intercept incoming reentry vehicles (RV) after they had descended below about 60 kilometres (37 mi) altitude, where the thickening air stripped away any decoys or radar reflectors and exposed the RV to observation by the radar. As the RV would be travelling at about 5 miles (8.0 km) per second, Sprint had to have phenomenal performance to perform an interception in the few seconds before the RV reached its target.

Sprint accelerated at 100 g, reaching a speed of Mach 10 in 5 seconds. Such a high velocity at relatively low altitudes created skin temperatures up to 6200 °F (3400 °C), requiring an ablative shield to dissipate the heat.^[1][2]The high temperature caused a plasma to form around the missile, requiring extremely powerful radio signals to reach it for guidance.

If you DO manage to achieve a really fast speed and survive, I guess you could always say "Now THIS is podracing!"

No, you'll just go to plaid

Why is this a question? We know reentry effects happen, have you never seen a "shooting star"?

You think they'd do that if they were just waltzng along at 5 m/s?

Of course the effects we see at high velocity in the atmosphere happen if you have a high enough velocity in the atmosphere... what is in doubt here?

The velocity required to see the effects is just much lower in KSP...

X-43A is the fastest level-flying powered atmospheric vehicle disclosed, and it probably gets just about to the point of causing plasma around it, but not nearly so visible as something like a re-entering spaceship.

Here's the video that picture is from(NASA Johnson's Youtube page instead of the Daily mail...to save from having to click to that site).  Pretty wicked.

The video begins 10 minutes before Orion's 11:29 a.m. EST splashdown in the Pacific Ocean, just as the spacecraft was beginning to experience Earth's atmosphere. Peak heating from the friction caused by the atmosphere rubbing against Orion's heat shield comes less than two minutes later, and the footage shows the plasma created by the interaction change from white to yellow to lavender to magenta as the temperature increases. The video goes on to show the deployment of Orion’s parachutes and the final splash as it touches down.

"Air resistance"? I guess. Depends on what you mean by that.

There is a misconception that high-speed aerodynamic heating is caused by friction. Most of it is actually caused by compression of the air in shock waves.
