And what are the chances if a missile disintegrates ?
the same as a meteor, which often disintegrate into meteorites.
They had their second unannounced test launch this week.
All meteors are unannounced.
You're far too smart for this silliness, Zeke.
you don't ever need to fly over NK, do you? I assume your airline doesn't service Vladivostok, so not likely, eh?
but you do overfly China, Russia, right? How about Pakistan, Afghanistan, Israel, Syria; do you get anywhere close to the US military? ... you have no trepidation about areas of the world mired in nearly continual conflict, and positively brimming with serious ground to air weaponry? How much of this gear do you suppose NK has (hint: very little)? Do any of these "ground to ground" missiles that NK fires off (in their fits of sabre rattling or effective extortion) have capability to track an aircraft, much less contain a warhead?
you know how a.net fully promotes (rightfully) the theme that air travel is far safer than automobiles, certainly motorcycles, possibly buses and trains? I can easily make the case that overflight of NK (test fires and all) is far, far safer than overflying several other countries that have busy air traffic (presumably ones you overfly).
who has shot down more civilian airliners since "The Korean Conflict" ?
4) North Korea
what's your hangup with NK?
