I couldn't cut together a good video to save myself, but I do have a grasp on how to obtain the aerial footage. I don't have much to add to this thread other than to say if you are trying to be an aerial operator, then don't worry too much about editing, spend your efforts on improving your footage and always knowing how to get interesting shots that engage the viewer. You are expected to be a master of your trade, not the editor or the creative director, but an absolute expert on cameras and everything about lifting them and shooting with them from the air.
Spend your time learning how to use your equipment to it's absolute fullest extent, and be prepared to use it in any shot you are asked to get. Always have an idea how to get the best shot with given lighting, subject placement, dynamic movement between camera and subject, etc. Most of the best shots we can get don't look like aerials at all, the best shots don't even leave the viewer asking "how did they get that", instead the best shots leave the viewer absolutely unaware of the camera movement and completely engaged in the subject.
The single most important thing is to learn how to use light. This is the most important thing in ground based photography and cinematography, and it only becomes more important when you put the camera in the air. Know how to light the subject, know how to use light to benefit your camera, know how to use light to obtain a certain look. Also learn tricks like how to hide the helicopter shadow and how to avoid lens flare when shooting towards the sun.
I read somewhere something like amatures worry about equipment, professionals worry about money, masters worry about light. If you are really good with light you can make go-pro footage look like a million bucks. If you don't know what you are doing then even footage from the most expensive cameras will look like low quality "video".
In the real world you only need the most basic editing skills to handle your own footage and quickly cut together very basic clips, in order to show your footage on a very quick turn around and verify shots in the field. For example this was put together the evening after the shoot and showed that night to verify the shots. It's not a polished edit, it's only intended to show the footage quickly to a few selected people.
On the other hand, when it comes to demo reels, unless you already have a good editing background then this is the time to spend money and get a solid creative editor to do the job. A common mistake I see is very solid aerial footage with a slightly armature looking edit, or even just a few small mistakes early on that ruin the feel of the demo reel. Your demo reel is something that should appeal to a wide range of people, that way it gets passed around, gets more hits, gets better search results, and eventually ends up being viewed by people who matter.
