Ok, so I went to dictionary.com to get some back up... Technically, pretty much any movement through the air can be considered flight. It can not however be considered jumping. By consensus of definitions, jumping is either powered by the feet and legs, or is sudden and fast. Destroy never jumps, it flies.

Also, quit being so cynical. SEED and Destiny have been very consistent in what constitutes a flight capable mech (we NEVER saw a Ginn fly, or any of the gundams in SEED fly unsupported, other than those speciifically shown to be flight capable. No inconsistancies). We see some mechs specifically designated as non flight capable (Gaia), and others with design mods specifically to explain their flight (Windams and Astrays have flight packs, Legends backpack looks ALOT like Forbiddens flight pack).

You have failed to show how my definition lacks... disagreeing with it is one thing, but show why its wrong, or where it fails.
