Euro,
There is an old aviation saying: The only way to become a millionaire in aviation is to be a billionaire.....
If you look at as a business, if you invest 70k how long before you earn that money beck before you are in profit???
Your options really are in the "so you want to be a helicopter pilot" thread.
You have to go down the FI(H) or IR(H) route. Unless you come from a military backround where you have to devote a lot of years to "Uncle Sam" first!!
Only one thing is true...nobody did it for the money
Including myself, first you do it because you like it and you will find your own way as you go along. it is better to try hard for something that you love instead of becoming another businessman(??).
That's my theory anyway
Good luck
