Careful now. That's just enough to cost you your medical, you know. Mental instability.
Much like your delousions of an exciting life.
If you want to play drama queen and yank the airplane around unnecessarily, have a ball. Chances are you'll wind up in one, some day. I've spent a good share of my career beneath powerlines within a few feet of the ground in a number of different aircraft, invariably in mountainous terrain, generally under adverse conditions...and still don't see it as a great drama.
Perhaps you're young enough to be just that little bit arrogant and just that little bit adventurous that powerline or pipeline flying really is that exciting to you. Good for you. Enjoy it. The truth is you sound like the kids who start banner towing and proclaim it to be the most dangerous endevor in this lifetime. Such inexperienced claims are a little like listening to a ten year old with his new BMX bike proclaiming himself to be the baddest boy on the block. The problem is that nobody really cares, and the youthful exuberance is okay for the ten year old.
Not for you.
Get a grip. It's pipeline patrol (which really doesn't differ significantly from powerline patrol by the way...been there, done both)...not combat. I grew up flying in the rocky mountains, and unless you were raised in the flats of Kansas, it's just not that big a deal.
If you're doing 90 degree banks while flying your pipeline patrol, it's a sign of inexperience, poor piloting technique, and poor judgement and skill. At least you've endevored to make yourself known.
