I am staggered that every inch of the rocket isnt covered by ultra high def cameras already to be honest.
What you can see with your eyes is not always that useful though. You'd be wanting all sorts of other sensors too anyway. I can't see static buildup, or a pressure change, until it has a physical impact on other things.Flooble said:

And as such being 'routine' probably isnt covered as well by spacex themselves.
Highspeed cameras are not cheap and scattering them everywhere would be a bit of a mission - remember they are likely to get damaged/toasted during this too..

You're right I forgot for a minute that this didnt happen during a launch!And as such being 'routine' probably isnt covered as well by spacex themselves.

SpaceX publish some information about their planned Mars mission, which on past performance by the company actually stands a chance of happening, and a lot of people seem very quick to criticise - I've seen a lot of very negative comments online about SpaceX's Mars plans

Apparently it is looking like a failure in the 2nd stage helium pressurisation system caused the loss of the Falcon 9

As I understand it, the helium tank is located inside the oxygen tank. If it loses integrity for whatever reason, the pressure of expanding helium will in turn burst the oxygen tank, with obvious consequences.
Edit to add: Yes, they are located in the oxygen tanks and are running at around 5,500 psi (380 bar). So no wonder they go off like a bomb if they let go. They're called a "composite overwrapped pressure vessel" (COPV) - basically a non-structural liner wrapped in carbon fibre.
Here's a couple of smaller ones undergoing destructive tests:

At the time of the Falcon 9 explosion, both liquid oxygen and helium were still being loaded into the upper stage.

So last time it was a strut holding the helium tank, this time it's the tank itself?
Somewhat simplistic. .http://www.spacex.com/news/2015/07/20/crs-7-invest...

The Muskmeister is going to talk about SpaceX's Mars plans at the International Astronautical Congress in Guadalajara, Mexico on Tuesday.
Starts at 7.30 pm UK time.
Should be rather interesting; "SpaceX" is short for "Space Exploration Technologies Corporation" after all.

Slight delay - should start any moment now.

Looks like a scene from "Things to Come", the 1936 adaption of HG Wells' The Shape of Things to Come.
I think Musk was inspired by Raymond Massey's character near the end.
