The RQ-170 was specifically designed with “mid-tech” rather than leading edge stealth technology, on the assumption that there would be occasional operational losses, so it’s unremarkable that in who knows how many attempts, Iran was unable to down one.

Or, you could simply been a case of mechanical failure.

You're confident that an RQ-170 was 'neutralized' in Iranian airspace. You know those details because you have SO much information and are privy to share that information with ALL of us, right?

And - without doubt - 'we' won't breath a word to a soul, eh?
