The lance was a downward orientation held in front of him, so all he'd have to do is move his arm back to get it into a throwing position. I would think someone could do a throwing motion in that length of time. He'd also simply land on his feet. Your mech was training his weapons on where he'd land, so if he was aiming I wouldn't think he'd be wildly moving the gun around, making it an easier shot and your weapon seems like it was a relatively large target and wasn't very far.

I'll edit the post to clarify his stance, although it would have to be in my post before last.

When you hold something like a spear extended out in front of you, you hold it in an underarm grip, this is completely different to the throwing of a spear, which is overarm. To swap grips you kind of have to chuck the spear into the air a little and re-position your hand, which would be nigh on impossible while falling at incredibly high speed, for a person with peak human stats.

My Mech is actually moving quite erratically in my posts, first of all it is running away from you, and then turning in mid-step and backing up further, considering your character has less than a second to react to this and position a throw, something so accurate seems unlikely for anyone of relatively human stats.

You can just edit the post where you launch the lance attack and adjust it to explain your character's position as he's falling. Let me know when you've done it so I can reply.
