If scientists are careful people, engineers are cautious people.
We went down to the Barnstormer's club official June meeting. We had two miniature wireless cameras and were ready to interview and send the cameras aloft. But weather intervened --- too much wind. And a bolt of lightning in the distance made the club president a little too nervous. "I'm not a risk-taker," he said. Engineers are cautious people (except the Swedish physicist. He was ready to go). They sure love our miniature spy video cameras, though.
