That's the thing though, what's amazing about planes really depends on your knowledge base or what experience is specifically being enjoyed. If you don't understand how planes work then the difference is moot because whether seeing or doing the entire thing is magical. If you do understand how planes work you might know that the crazy thing isn't flight, we knew how to do that since approximately 1800 when the first gliders were built, the crazy part was generating enough power to make powered flight possible. If you understand how flight works and are still enjoying the experience of flight is where wonder still exists.
You know the wonder of flight still exists because some number of kids and adults would pick flight as a super power if given the choice.
You might be right that it is an implicit threat and as a threat it constitutes verbal assault, but you'd have a hard time making any real headway in court with that, especially in a he said/she said situation. It might be a crime, but it's one which will see almost no prosecution.
