The curved blades of this jet engine are shaped very precisely
           JET TURBINE to catch the air, and they are also strong enough to stay stiff
           when working at high temperatures. There are several tough metals that fit these requirements,
           but most are very dense, making them too heavy for an engine powering an aeroplane into the air.
           That leaves only one metal for the job: aluminium.
