alarming rate. The young ones dont want to be tough hand skills any

The trick with rocket engines is to prevent them from burning themselves up
while burning the maximum amount of fuel. Therefore, it's a complicated
fluid dynamics/thermal management problem, with fuel lines cooling the
combustion/expansion chamber, turbo pumps working against pipe and flame
