I would love to fly low as long as I could pick the airplane...SuperCub, Husky, or perhaps an old crop duster that is no longer feasable - like an Air Tractor 301 (wouldn't work - low wing).

So, as you are flying over a pipeline, what are you looking for (what can you see about a leak from the air - dead vegetation?). Specifics would be great.

How many times do you fly a day?

Can I buy an old Cessna 140 and get a contract to do this myself? That would be awesome!

What kind of weather do you fly in, and what happens if you are unable to fly - ground checking?

de727ups also has a good question - what would they look for with powerlines?

Sorry for all the questions - just very curious about this.
