S: Atmospheric contracts.

[Sereneti]

There are the Goliath engine.

a good engine, have a lot of thrust but on the other hand have low speed.

a good engine to carry a lot of payload. like a "jumbo airplane".

atm in a normal carrer game , useles.

my suggestion is:

Make contracts that fit onto this engine.

Like: "build a station on the north/southpole dessert ... " ...
"bring tourists to this koordinates."

"bring this rover to this koordinates"

"we want to build a new center. we need recources on this koordinates (ore)"

and so on.
