It's mystifying that any airport with commercial service doesn't have cameras with a full view of every runway recording 100% of the time. You can't steal a catalytic converter without being on video. We have webcams placed behind eagles' nests in our national parks. Yet somehow we have no recordings of plane crashes at our airports. Then of course there's the lack of cameras on the planes themselves...
Also, I've flown a lot of Korean Airlines flights where they have front, down and side view cameras that you can watch on the entertainment console. I'm sure it's just a matter of time before more airlines adopt it.
