As long as you have the infection test facility from an infected event you can always try for an infection that will result in a flying unit (see other pages on the wiki for the best units to infect for the highest chance of success at a flying unit).

If you don't have the required black nanos to use the facility, you will be prompted to buy them with regular nanos.
