Most of the accidents you hear about relate to the many unusual and varied tasks that a helicopter is capable of performing. Of course we can't always choose our flight weather conditions. Most times we are able to fly around poor weather, but if unavoidable these conditions are rarely a problem. Lightning is usually not an issue because it needs a ground to transmit to and an aircraft, although electrically internally grounded, is not seen as a true ground. Rain does not impair the performance of the aircraft, though is does temporarily affect visibility.
Helicopters are surprisingly expensive to purchase and maintain.
Aircraft manufacturers are under so much scrutiny and liability that they have to charge a large portion of the purchase price just to allow for product liability and outrageous lawsuits. There are many airports large and small scattered across the Country. There are also many helipads available depending on whom you know. Any landing sites outside of those which are approved can usually be arranged. First and foremost the landing area must have a firm surface and be free of trees and wires in at least two directions for 100'.
