Quote from ikuyoK
And Ace saw something falling.. Kinda hard to tell if it is Luffy at that distance really. But I'm sure if he uses his fruit to save everyone then Ace will be able to tell. Third gear giant ballon?
A Giant Balloon makes sense, but in third gear his Gomu Gomu no Fuusen (Balloon) becomes Gomu Gomu no Hone Fuusen (Bone Balloon) and hard enough to deflect bullets, so he'd essentially turn into a huge meteor instead of a balloon.
Kuma could probably save them somehow with his fruit ability, considering what side he belongs to is still ambiguous (to me, at least). Crocodile could be able to save them with his sand abilities if he copies Gaara and does a floating sand thingy, though whether he'd actually want to is debatable. Honestly though, this is Oda we are talking about, so anything could happen.
