A number of professional pilots have a fear of heights! In an aircraft they are fine (breakoff phenomenon), but get them on a ladder or on a high building and...Yike! I am NOT a fan of most of these tourist helicopter outfits. Their maintenance and the judgement of their pilots can leave something to be desired! "Go fever" can lead to disaster, as illustrated by the crash with the late Kobe Bryant. The pilot should have politely, but firmly declined to fly into IFR conditions! Definition of cumulo-granite: A cloud with a mountain in it! And, no, helos in general don't scare me. I've been a passenger in several when the pilots had just returned from 'Nam and decided to chase coyotes around the Montana countryside, enroute to or from a missile site!
How does all this relate to model railroading, BTW?
