We see this case often: sucessfull professional realize he/she really wanted to do aviation but life has changed and either familly, age and other things make it complicated.
it is realitively heart breaking because there are great rewards in familly and a stable job but at the same time nothing can replace an unfullfilled dream.
I would add a point, flying helicopter as a job is not always as great as pictured
_ pressure of the boss (risk management)
_ unfriendly hours or location
_ repetitiveness (tours)
_ low pay (compared to your current position)
_ ultra low ramp up (you really have to pay your due in the hardes ways as an instructor and so on)
working toward private helicpoter ownership, and maybe doing a few side helicopter tasks, and maybe find an angle and get an AOC...
is also an option, fly when you want it, during nice weather only, improve your skills, meet great people...
