I am working on some concerns about my husband's flying. He is quite intelligent and capable, but he glazes over and waves me off when I try to bring this subject up.
One of the things that brought me to GA besides the glorious freedom and power of the control of a plane is management of risk. IMNSHO, the management of risk for people is something they can't often put into words. I used to enjoy motorcycle riding, but I was always on edge a bit due to the concerns of the drivers around me, and the designers who made the roads. I had to assume or accept the risk but I had little or no control over many segments of the activity.
In GA, we have a great deal of control over our assumed risk. For me, I own the plane, I maintain most of it, I fuel it, clean it, prep it, check weather, check my route and navigation, I verify the conditions of myself to make the flight and basically, without going into the engine itself or the flight controls, I manage pretty much every aspect of the risk. If there comes a day when I don't check the weather and find myself in the soup as a result, there's no one else to blame, and I'll do my very best to reduce that risk. I think most pilots think somewhat the same.
There is no life without risk. People have died falling out of bed. People have died on the toilet, and have died sneezing. Sure, flying GA is more dangerous than sneezing but it's a heck of a lot more fun(although a good sneeze is nothing to 'sneeze' at, lol).
At the risk of reaching into your marriage, I would postulate that your husband tries to wave off your concerns because you sound more and more like a harpy, shrew, and have become controlling or manipulative(in his eyes) regarding a 'decision' he has already made.
I love to ski, and my wife wants no part of it. I'm a good, fast skier and she's seen some videos of my ski runs. They seem to scare her a fair amount, and possibly with reason cause I've had a torn ACL and a broken leg in the past 14 years of skiing. That means there is risk, and once in a while she'll make some uninformed comment about my ski trip that sets me off. First, because it's ME taking the risk, not her. Next, because she is uninformed about the risk. Finally, I already had a mommy and she's gone now. I don't want a mommy at home I want a
wife.
So, give him a hug, a smile, tell him to have a good time, call if you like and live with the flying situation sans comment/concern. Or --- don't.
