Could the mystery aerial objects end up as a damp squib?

No one yet knows what these three aerial objects are or were before they were shot down by US fighter jets. But there is now a chance, oh dear, that they could be unrelated to the Chinese spy balloon, despite the incredible coincidence of their presence in the air so soon after the spy balloon arrived. And may be, just may be, they could be innocent balloon-type research vehicles launched by some American company. If this turns out to be the case, why has no one stepped forward and admitted these flying objects belonged to them? It really would be a damp squib if these things in the air are nothing to do with espionage, let alone Chinese espionage. Now we hear that in one case the US Air Force fired two missiles, not just one because the first one missed. So that means the Pentagon has spent around $1.3 billion for no reason, and that's not counting the cost in fuel involved in having so many aircraft engaged in the mission to track and destroy the objects. I mean, to be honest, it's the best end to the drama because they weren't all super secret Chnese spy machines but it could be one of the biggest anti-climaxes of all. But the huge spy balloon was a real espionage operation, right?
