Oh yes i'm sure that it does. I know lots of airline pilots who also have shares in light aircraft, as they miss the fun of flying 'little ones' and being able to fly exactly how you want and not having to fly to company standards.
I wonder if some airline pilots feel a bit disenchanted having put in so much effort and money to get where they want to be and feel 'oh is this it, is this what i've put my whole heart into?' and feel a bit disappointed when the buzz has gone.
