Number on fuel tank?

[Redrobin]

So I was launching my rocket and I noticed this:

Do these letters and numbers mean anything?

[kenbobo]

I dont think so...

[FenrirWolf]

It's just the official name or designation of that particular part.

[Superfluous J]

Yeah, but they could have put anything on there. Maybe the letters have some joke meaning?

Maybe someone's dad's initials are KA and he was born on May 6th, 1932. Or June 5th. Or March 3rd 1956

[problemecium]

Nope. Definitely was born on May 2, 1963.

The sum of those numbers is 7, which is a lucky number.

5+6+3+2=16.

1+6=7.

The hexadecimal conversion of 5632 to a string is "V2".

[That guy who builds stuff]

They're not important in game, but those labels are often a reference to something.

[Darth_Kerb]

The hexadecimal conversion of 5632 to a string is "V2".

This, given the fact that the FL-T100 is a very basic part, might be the answer. Now we only need to figure out what "KA" does refer to.

(btw I love those little references on the parts)

[O-Doc]

My guess would be Kummersdorf Aggregat...

[Kasuha]

There's "KB 6551" on FL-T800 tank

[O-Doc]

Wild guess: Type-K Boron Thermocouples, http://www.google.com.au/patents/US2946835

[O-Doc]

Maybe it relates to the space-time uncertainty principle...

[O-Doc]

Ok, last attempt. In 1965 the ruskies launched the maiden flight of the Soyuz/Vostok 11A510 at the Baikonur Cosmodrome(úþÑÂüþôрþü «Ã‘ðùúþýур» or KB). Possibly 51 in 11A510 represents the block number of the production run.

I think they just have a cat walk over the keyboard, but it's just a theory.

[KvickFlygarn87]

Damn, now I'll have to start looking for an answer to that :-(

[EdFred]

I never noticed that on the fuel tank, but on the science lab they have the dates corresponding to ISS and Mir

[brianorca]

My favorite is the 2-Kerbalnaut lander capsule is labeled T-C4N

[flightmaster]

Well if you add 5 and 3 together you get 8 which is half of 16 which is the date in November that Half Life 2 was released on and if you divide 6 by 2 you get 3. It's a clear reference that Half Life 3 is coming out soon.

The hexadecimal conversion of 5632 to a string is "V2".

or {synchronous idle}{null}, depending on how you interpret it!

[Kasuha]

KA 5632 is a full extension drawer slide...

[Koltronn]

KA 5632 is a full extension drawer slide...

We have a winner, The KSP devs have always been raving drawer fans.

[Tortoise]

Kerbal Astronaut?

Kerbin Atmosphere?
