CHEMICAL ROCKET

Gas heated by a chemical reaction provides thrust. Rockets remain expensive and prone to failure due to ablation, extreme vibration, and the use of corrosive and flammable chemicals.

Rocket type

1 failure for how many launches

Atlas Centaur

1 failure every 7 launches

Titan

1 failure every 13 launches

Ariane 4

1 failure every 90 launches

Airliner

1 failure every 10^6 flights

As you can see, rockets are dangerous engines. One failure here mean destruction!

As you can also see rockets must also be big!
