Well the first one is easy! I have always loved aviation there is just something about it, as for helicopters there is just that extra bit of excitement, problem solving on the next level and more things to watch out for.
The second one is a lot more tricky. A lot of the time it is the last flight, there is always something new, a ridge to conquer, a slope waiting to be tamed or a volcano to be watched.
Happy flights and merry Christmas!
