Nice, vanilla friendly and ellegant (even if the interception window looks a bit worse) feature and all, but... the thrill of not being sure will be gone... Something will be lost... After all, IRL a pilot wouldn't be able to tell if an UFO shot down at 10km attitude will fall into the sea or not, if it happens within a few kms of the shoreline... I dunno, maybe I'm just getting old... But this is going be just an option, so let's just call it "casual mode" and not use it if do not want.
And yeah, I don't intend to play TFTD anyway, especially after Hobbes imported the best part of it (urban terrains), and Solar has imported most of the TFTD aliens. Although I support its developement, as it promises a single saving grace: potentially definiable special enviros (if underwater, then why not space? Low-G? all kinds of hostile enviros?)... if it gets broadly implemented instead of just glossing over it like Microprose did, that is.
