Maybe those fighter pilots who were seeing those really oughta try shooting them down, just to see if it works.
Humanity at its most basic: Hey, look at that weird thing! Let's try to kill it!
Look man, sometimes the only stick you have on hand is air to air missiles and/or more traditional heaps of flying metal. I'm pretty sure accelerating a stick fast enough to hit one of the things wouldn't make a substantial difference in regards to provocation.
... that said, the thought of military jets getting installed with lumber launchers for purposes of poking UFOs with a mostly literal stick is fairly amusing. Bonus points it'd probably be decently effective for ground support operations. If furry midgets can manage to take out AT-STs with logs on ropes surely launching them from a mach whatever jet at a building would do just fine, right? There's nothing wrong with that logic whatsoever.
Slightly off topic... but something just clicked in my mind. Those Ewok's traps must have taken days... weeks to set up even. And they were set up in the area RIGHT around the entrance to the base under the Scout Trooper's noses, tailored specifically to defeat the forces that were there and brutal in their efficiency.
Combine that with the fact that when the Rebel party were originally caught and before C3P-O did his god impression, they were about to cook and eat Han, Luke and Chewie...
Those Ewoks were god damned monsters, stealthy, violent, effective, and strategic geniuses to work with what they had. It can only be assumed that had the Rebels not shown up, the Empire's forces on the moon there would have been attacked anyway in the coming days and been killed, cooked and eaten.
...I never even considered it in that light... and makes me feel completely different about the minimal casualties they took in the battle.

Republicans are apparently preparing their own bill to replace NN with something weaker, while Schumer just wants to go back to status quo. As much as I hated the FCC vote, enshrining it into law is so much more permanent. Even just rolling back to pre-Pai doesn't necessarily protect much.
