F2
==


`Fluorine (F2) <http://www.astronautix.com/l/lf2.html>`_ 
engines have been developed and fired successfully, 
although none have yet flown in a space mission. F2 is very high performing,
and very reactive with virtually all fuels.

Being cryogenic, highly reactive and toxic;
handling and safety considerations have hampered its use in liquid rockets.
