And, Here is my Waverider Class entry, It topped out at 4016m/s.

Okay, here is my Hermes Class entry. I topped out at 4067m/s below 50km.

For the Hermes, are we allowed staging? Like to drop spend fuel tanks?

Alright @JacobJHC, I believe I have accomplished this challenge (before I knew it existed). - Which game versions did you use? 1.8 - How many Kerbals are on the mission? Just Jeb - Did you needed a refueling mission? Nope, and I did not mine either. - How many launches were needed to start your mission from Kerbin? Just one big launch. - How much did your mission cost? IDK - Did you bring additional stuff like satellites, rovers, etc? Nope, bare bones. I did give all of the detachable parts antennas and power so they would function as relays after I discard them. - Share the delta-V information too, if you tracked it! DeltaV is always shown in my KER readout top left. - What mods did you use, if any? KER, Mechjeb, Trajectories, ReStock, Better Order of Parts... maybe something else... Nothing that changes physics or adds parts. Yes, I have HyperEdit installed, I used it to test ships but not to fly the mission. Enjoy!

Yes, all of my physics and parts are stock. My parts look a little different because I use "ReStock", I think that is also the mod that is changing their names. I also use "Better Order of Parts" which might change their names, I'm not sure. Kerbin looks a little different because I use "Scatterer" and "EVE."

If using 2 SRB rockets to destroy the VAB is good. Surely using 12 to strafe the hell out of KSC is better! So much destruction!!!

Here is my 50 seat SSTO in career mode with paying tourists on board. Of course with a landing back on the runway.

Yes, It is still possible to destroy buildings in 1.8.1 sandbox mode- but it takes HUGE energy Here is a video.
