A B777 sure can't. And that's what we're talking about in this thread?
This is what confuses me. Assuming they have a half decent military radar system they will
know or not if MH370 crossed back over the country. That is why they are searching there after all...but if they
know this then why still bother to search along the flight path and up towards HK.
Unless they don't actually know anything more than FR24!
