When Havoc Struck

I would like to see this series again. I remember it being shown on Saturday teatime in the UK (BBC must have needed a suitably frightening substitute for Doctor Who! - unless it was the independent competition) under the title "Havoc". I was amazed at the footage they showed at the time, particularly the man falling from the airship, and the motor racing episode. Some horrendous carnage.

I can completely verify the comment above about the 'sting', it is still with me 30 years later.

Anyway, I missed the last episode, I think about earthquakes, and have been looking out for it ever since, but has never been repeated.

Were there 10 episodes in total?
