What are the Land and air speed records

[Taki117]

If you are asking what they are, I have no idea, I know some of them, but not all, like there's one for 250m/s, 5000m from the space center, 11km altitude. Quite honestly though it's irrelevant. Accept the first couple of contracts (Usually launch a vessel and collect science data) and you will get the altitude and speed records automatically as you progress.

i mean like what are the fastest people have gone on land and in air

You want to check the Challenges section of the forum for things like this.

The fastest surface vehicle I know of was about 450m/s, I think that was in a Scott Manley video though (and may have been before 1.0).

As for in air, it depends what rules you're setting. Is re-entry allowed, or are you talking about planes below a certain altitude? Re-entry could be up to any speed really, including speeds higher than lightspeed. Atmo-only aircraft will be limited by thrust:drag ratio and obviously too much speed would result in orbit. The fastest I've personally ever flown on jets only was 1800m/s but that was back in alpha.
