In addition to my responsibilites in aviation, I'm also a volunteer firefighter. We get called out many times for emergencies which either are not at all, or are not what they sound like when the call comes in. Always remember that most of the calls for emergency services are placed by people who are stressed, and not sure what, or where the emergancy is.
Today, we responded to three false calls. One an over heated car on the side of the road, which the passing caller said was "on fire". We ran four trucks and ten firefighters to that one. The next two calls both needed me to fly, in addition to the other responding personnel and equipment. It was a good day, nobody actually needed our help! But we were ready in any case!
We would all much rather overkill than underkill, in provision of service. After all, if you were called to a "plane crash" how much equipment would you take? How big is the plane?
