1/5 scale space shuttle
The main motors (6 contrail O motors) are about $2500 each and there were over 20 CTI motors of various sizes. Not cheap and the explosion at the end was staged. It was actually a 500 lbs bomb test that had been dropped on the same location but at a different time.

The liquid "fuel" in the motors isn't actually fuel. Its oxidizer. N2O decomposes in heat (+300 degrees C, don't remember exactly) into 2 N2 + O2 The O2 is used to oxidize a fuel. Normally it is either PVC, paper, wax or acrylic. It can be (but normally isn't) a very low oxidizer solid propellant like APCP or ANCP or KNCP
While the N2O will burn (decompose) in the right conditions, it will almost never explode like shown in the video. It was very impressive, but not real (from the rocket motors)
In rocket motors alone, they more than likely ended up spending in excess of $20,000 which will never be seen again as the re-usable motors were destroyed on crashing into the land (it did crash, but didn't explode)

I didnt catch that it was a hybrid, I know how they work but its a good link!
I thought they used a big "liquid fueled" rocket like liquid oxygen and liquid kerosine/hydrogen or other fuel...
The solid boosters detatched, did they have a parachute like in the drawing?
Well still impressive that the car lifted off, or was that fake too?

Sailing Student- How do I know if my life jacket is tight enough?
Me- Can you breathe?
Sailing Student- Yes
Me- Then its too loose!

The main motors were hybrids and while most people not into rocketry would think they're liquid fueled, if you're talking to someone with rocketry knowledge, you call them hybrids to keep the confusion to a minimum.
As far as I know, everything was real with the exception of the explosion at the end. Unless you have high explosives (like in the bomb) or a true liquid fueled rocket (LOX/fuel) then you wont get the large fireball.
It was TV, they had to make it exciting.
