Blowing $20,000 worth of Fireworks up in 10 minutes .......
Used to run a Fireworks company doing public displays. Could be quite entertaining for the operator down in amongst it all. Still got the cotton overalls with the holes burnt all over them ..... lots of close call stories there, Fireworks are not known for their reliable operation. 'Duck' bombs were the best.
Then when that slowed down moved into Amateur Rocketry. Gave it away after the second big explosion in the back yard testing a tethered motor... neighbours objected .... funny that ..
A bit of Rally Car driving, some track time,

Water Safety Patrol Skipper, crashing about in the Hauraki Gulf in a 2 tonne 43 knot patrol boat looking for idiots who go to sea in storms.
Yeah, been a pretty quiet life really...
