LOL! :D

Edit: If you can survive for 5 seconds, then you are not trying hard enough.

P.S. How about separate leaderboards for survivable and not-survivable entries.

Good idea. I will add that.

Can I steal other people's old Land Speed Record designs and post them here?

As long as you give them credit, I am ok with this.

I forgot to add, I did challenges 2 and 5, well, for 5 I included 4 and passengers, not 2. Not sure if that counts or not.

I will add 5, your craft still has launch clamps, which counts as a stage.

Can we use mods for flight control?

Okay, I have an entry. No mods were used in flying the craft:
1980 m/s.

SPH shot:

Prepare for eastward takeoff from the Island runway. Having a big discardable wing helps a lot.

We know we can't land, so better to get ready to bail out after the run.
Xb1i4Lb.png

We hit 700 m/s, our drag-limited top speed. While the heat shields are not producing significant drag due to some node shenanigans, the NCS adapter is limiting out speed. Time for the rocket stage. Stage separation is aided with two ullage motors.
OobjIT1.png

1978 m/s. Right before it flipped out.
WHiLvUb.png

Several explosions later, we open the service bay our command chair is in.
MPuqoHb.png

Bailout successful. Parachute deployed. Still at a very high speed though.
jYioJaF.png

1980 m/s top speed and we stayed under 400 meters.

I suspect we're not even within a km/s of the best possible, considering that the ground speed record is at least 3500 m/s, we are on the equator, not the south pole, and this design of mine was very much a first attempt, not a full-optimized design.

Frankly I am surprised this even goes supersonic. Current issue is structural: the craft is very likely to rip its wings before I can get it to top speed. I may try removing some of the fuel.

Not an official record because I used a mouse-aim flight mod and went above 600 meters, but a launch abort that beat the record by quite a lot.

A conservative run of the actual thing (resulting in an unplanned failure but who cares). 2428 m/s.

Throttle up!

Supersonic.

This thing can do at least twice this speed before stage separation, but again, conservative run.

Pretty sure Stratenblitz has done escape velocity at sea level.

Yeah, here's the vid. He went to the polar ice cap for the 3469 m/s run.

No, as it is a pretty large part of the challenge. Though feel free to try, and it will be included in the mod leader board.

If you want your craft added to the leader board you need to fulfill the requirements set in the rules. And avoid part clipping (fairing clipping engines). 
Though I am seriously impressed by the speed you accomplished.

He accomplishes the speed by clipping several nosecones into each other to reduce drag and provide a powerful heat shield, also the sepatrons are clipped into the body to reduce drag. 

A seriously impressive feat, but still not meeting the challenge requirements.

The actual run has no fairing. Sorry, should have clarified.
