Yes, that what I have heard as well. It is so sad. And I have to agree with you that a machine should be been better able to detect the presence of a human being.

Perhaps in the future we can build in the technology to sense a beating heart or other bodily functions (sight, sounds, and/or smell) that the human body would emit. I'm no scientist but I'd love to run that one by some really smart scientists and see if they could come up with something.

Thank you for the comment, @gikitiki. Nice to have you visit.
