You know you're a noob in KSP when...

[Nansuchao]

You know you're a noob when:

You begin in KSP with no knowledge of anything and spend hours and hours on YouTube and forums learning from experienced players, spend hundreds of hours in KSP testing, learning...

You're finally able to build your ultimate super-mega-ultra SSTO, you test-launch it to Eve, and when you successfully land after a perfect aerobrake, you realize that you forgot ladders!!!!!

[Toastedbuns]

You know you're a noob when you lithobrake with command modules filled with kerbals.

[LethalDose]

"I keep going higher and higher up but I'm not getting into orbit! What am I doing wrong!?"

[CelticCossack51]

You know when you're a noob when you leave infinite fuel on forever.

[KerBlam]

What is Delta-V?

[Gargamel]

You know when you're a noob when you leave infinite fuel on forever.

Not always a noob does this, had IF on for some reason, then switched over to a new launcher, trying to test staging. Took me a a while to figure out why it wasn't staging! lol

[Scotius]

You know you are still a noob when after a set of maneuvers you land your probe on Mun's pole, at night...only to discover you've forgotten to install that one part needed to fulfill a juicy contract.

[Hary R]

"Hmm! My first plane in this update, let's put it on the tarmac and see how good it is.... What? flame out?"

Yes sir, jet engine need to breath... Your are a noob if don't see what i was doing wrong.

[samjohnson]

When it takes you nearly a year of trying to reach orbit.

Definitely not me!

Ok....

Maybe it was...

[RAINCRAFTER]

When you try to land on Duna without Nukes and without doing an unmanned mission before this new manned mission.

[Souper]

When you underestimate the realism of KSP and try to land on the mun with parachutes. (not gonna lie, i fell victim to that myself when i was a noob.)

[Olterin]

When you don't test your parachute deployment plan for a Duna landing, and then sometime during the landing, on IVA, you hear a sudden *boom* after you deploy the chutes.

... It was totally not our ascent stage, was it? And what's this thing flying off towards the ground at a high velocity?

[Frank_G]

...when you bring your atmospheric spaceplane all the way to Duna and wonder, why the jets wont fire...

[Talavar]

When you think all you have to do is point your ship at the moon and thrust, and you'll get there. lol (Did this when I first started playing orbiter simulator about 8 years ago)

[Frank_G]

...with the Mün being the only celestial body, where this actually works

[SmashingKirby148]

.. when you go to Jool, and have a very low periapes and you are looking in the map view only to find when coming out, there is nothing, then you move the camera and BAM. Heart attack-from-seeing-something-gigantic kicks in

[Cripion101]

You know you're a noob when you get past solid rockets and try to launch your first liquid fuel rocket, and can't work out why pressing space doesn't turn it on.

(It was a long time ago alright?)

[Seanoog]

After 3 years, I have only now succesfully learned to dock.

Granted I learned with two large space stations, each weighting over 100Tons, and have been doing it every day, to improve my technique...

An amazing sense of achievement.

And no innuendos..

[Alchemist]

When you dock like that:

rendezvous achieved

lowering relative velocity and pointing it straight at the craft

entering visual range and correcting for proper approach vector

minimizing relative velocity

alligning to the docking port vector

entering perfect final approach vector

wait a minute... It's not the right craft!!!

[Yemo]

You refuse to use mods because you want to play the game as it was meant to be played.

You fear that mods upset the "balance" of the game.

[CrazyJebGuy]

When you are competent enough to know what periapsias, Delta V, specific impulse is, but you can't dock and have not gone to any planet other than kerbin.

When you are trying to land an underpowered lander and you think: It's ok, I got plenty of time.......This is slightly alarming.....AHHHH! MOAR POWER!!!......BOOM!

When you get into orbit, and don't extent solar panels. Or forget SAS. Or balls a minmus landing cus your transfer stage had 5k delta-v left and you don't want to waste it, so you release it too late and boom.

[Mr. Scruffy]

You are probably still new to the game, but may have played too much recently (aka ´honeymoon-phase´), when, driving through a round-about in your car, you try to leave it, by pushing down the gas real hard. I almost did that once.

[Temeter]

When you are trying to land an underpowered lander and you think: It's ok, I got plenty of time.......This is slightly alarming.....AHHHH! MOAR POWER!!!......BOOM!

The only difference here is that pros don't even bat an eye when that happens. KSPs height indicator can be very misleading, since it switches very late from sea to ground-level.

"Yeah, I forgot how to fly this thing properly," I sighed and pressed F9. It always happens with my nuke-powered lander, I usually have 1 crash when starting to use it again after some long delay. Other than that, it flies perfectly

What do you mean? The altitude displayed on top of the screen in vehicle view? That one should always be displaying sea level altitude. The true altitude radar altimeter in the cockpit IVA? That one should always be displaying distance to the ground, albeit only up to a few hundred meters.
