Yeah I wonder for how many seconds it was there, since you can't even count it in hours, but "UFO" is still there as the biggest news in world as you can see in my screenshot and also by visiting the page.
For instance if I would not be BANNED from posting links on HN I'd post also this which I find more interesting news affecting everyone than some dumb made up baloons which are on par with Iraqi WMD
But aparently I'm ALWAYS posting too fast only when it comes to posts, but have no such problems with comments, it's sad how low can go HN in shadowbanning users without transparently communicating why is one banned from something.
It was on the AP front page. But is no longer.
