Man on the moon Is a question of best practice, In 1969 ships still ran on steam, ....snip... Just think we Brits could have beat the US to the moon.

OUCH.... that hurt ....I fell off my chair laughing. You Brits also could have won that one war back in the late 1700's also, but you didn't.


You cannot be serious? There are so many errors in your thinking.

Any engineer in all honesty will tell you that ships have NEVER run on steam. Things have run on coal, wood, fuel oil, or nuclear power for years. Ships or trains or automobiles or farm equipment or factories etc. have never on steam. Steam is simply the media used to transfer heat energy from any source to rotational mechanical power through a piston/cylinder, or a turbine mechanism.

Jet engines have been around since 150BC. If you are talking about jet turbine engines they are a bit newer. Serious development taking place in the early 1900's and began flying in the 1940's. YES, jet engine designs are still being developed and improved. They are better now than they were in 1969. They will continue to improve.

The same is true for internal combustion engines. They are constantly improved and made smaller, use less fuel, more power, more reliable.

It is the nature of mankind to seek better ways to do things. We do not always succeed. Sometimes we take a step backward. Sometimes "we" do really stupid things. But then it is easy to look back and see the errors made over the years.
