We often try to post videos that explain things in the news.
So this is what we posted when the UK's airports were closed down by a huge cloud of volcanic ash from Iceland.
We posted the video within our Sixty Symbols project, because it loosely fits in with a bit of physics (mainly via an engineering angle).
Aircraft safety (and crashes) is bit of fascination of mine, so I enjoyed chatting to to Colin Foord, the jet engine expert featured in the video.
The 1982 incident over Indonesia is something I've watched countless times on Aircrash Investigation (possibly my favourite TV show!)
