Can't the escalator like flatten out or something awful, when it's without power?
No, but that would be very funny
You're right they don't flatten but the brake does have to engage to stop it from behaving similarly to a manual treadmill
escalator temporarily slide
No, this particular escalator does not include emergency slide mechanism, although this would've helped OP in such troublesome situation.
Wouldn't that take ... like ... power?
