I think the implication, with all due respect, in the way you worded
your post, is that the probability is increasing as you flying time is
increasing.

It depends on what you mean by "the probability". There are two
different probabilities being discussed: there is the probability of a
failure on any particular flight, which doesn't change, and there is the
cumulative probability of experiencing a failure on some flight, which
does change (it increases with each flight).

This is clearly not the case, as I think we all now agree.

Your statement is ambiguous because you don't say which probability
you're referring to.

Every day is a new day, and N gets reset to zero.

Not quite. Every day is indeed a new day, but with every flight N is
incremented by one.
