probably a hobby but a 421 is a high performance dual engine with a pressurized cabin... that's a lot of plane and dual engines are difficult to fly with a lot of technical knowledge and practice to handle an engine out procedure safely. this kind of plane very commonly kills doctors and other high earning individuals that don't have the time to keep their time in the plane to stay recent.
a lot of time people do buy multi engine planes for travel so it's not certain it was just a hobby.
