Hi,
Thanks Andrew, was that your video of funnel cloud on channel nine news last night?
I've been admiring your work, you're certainly dedicated to it.
Worked out how far away that strike was, with the speed of sound through air at a temp of 20 degree's celcius being 331.5 mps, I timed the flash to the lightning strike to to the thunder of an an average of three timings, of 4.9 seconds.
Comes out at approx 1.6 kms away.
That's close enough!
Cheers,
Justin.
