Those seem like good guesses. Either seems plausible to me. It does some weird mid-air pause thing at 0:32. And generally seems to be going horizontal or even

Those seem like good guesses. Either seems plausible to me. It does some weird mid-air pause thing at 0:32. And generally seems to be going horizontal or even increasing in altitude. Maybe that's just momentum? It could also have tiny wings that are catching some air? But it looks very symmetrical and also reflective. The drop tanks I could find all look more aerodynamic and dull. I couldn't find any good videos of drop tanks being dropped. Not sure what kind of supply canister it could be. I'd love to know definitively because this is the first video I've seen that seems at all interesting.
