Recently while playing Hightower I charged a Pyro while being air juggled with successive back blasts. Usually the charge is a good way to escape an air juggle, but I seemed to get caught by another back blast before I could escape the juggle.
So that makes me wonder, can the Demoman's charge be back blasted by a Pyro?
Also, does it matter whether the Demoman is already airborne?
Can the entire charge be back blasted, from start to finish?
