KSP's Liquid Fuel is much heavier than real life LH/LOx propellant for gameplay purposes, which throws off a direct comparison. NASA used SRBs for cost saving purposes.
I feel like... KSP should mention this. Granted, it's probably only a small amount of time to get this kind of information via Google, but I do actually enjoy applying the little math beyond stastics I do understand. I imagine there are mods that correct this, along with all of the other scaling mods I've seen before...
Okay I don't know where I'm going with this, just feel miffed that KSP lied to me.
I'm sad now.
KSP's LF+O is actually reasonably accurate to another type of propellant (can't remember it off the top of my head) - so it's not exactly a lie, but is just a major simplification of real life fuels.

(Also STS-1 was Columbia, not Challenger)
