Airplanes are not go anytime, go anywhere vehicles.
My airplane is a good example. If the weather is bad you cannot fly. Flying a small Cessna in severe weather can be extremely hazardous to your health.
I remember one time when flying in bad weather, I got stuck in Clewiston, Florida for a couple of days. I was lucky. I landed at the airport before the weather got so bad I would have been forced down in the Glades. The Everglades is no place to be forced down, anytime, let alone in bad weather.
