You made the assertion that basebands remain in contact with towers even in airplane mode, and so can be tracked. Someone asked for supporting evidence for that claim. You've responded with examples and links to different issues. It's a fairly extraordinary claim (it's not one I'd heard before - it's clear that other radios may remain alive for various purposes even when airplane mode is switched on, given that you can use wifi and bluetooth on planes, but you're the first person I've heard make this claim about the cellular radio), and you haven't provided any evidence to back it up at all.
