Flight and knockback

[Ramesses]

If a hero is in flight and is knockbacked dose he {she} hit the ground or is she still air born on a unaimed hit. we looked in the BOOK of knowledge and it is vague in that aspect of it

[Steve Long]

It's vague because there's no specific answer. It depends on too many factors to answer definitively. Most importantly, look at the angle of Knockback; a character Knocked Back upward from the ground certainly won't fall to earth, while one blasted from above very likely will. But if the character uses movement to brace against Knockback, that may change the equation; other factors could also play in.
