Flight in the free-to-download game C-evo becomes available (as with most other Civ-type games) in mid-game, a little while after you or cooperative friends have researched Chemistry, Explosives, Physics, and Refining. You may have become able to build a glider earlier by building Leonardo's Workshop. Unless really keen to do long-range scouting or blocking of enemy units, by adding only fuel modules, you may be wise to delay air unit development until you research Advanced Flight.
The Standard AI in version 1.2.0 is unable to create air units, which gives human players an advantage, because air units are the only units that can destroy air units.
