What exactly do you want to use the camera for? Is it [mainly] for filming flights? If that is the case, what you really want to look for is a camera with built in OIS [Optical Image Stabilization] on the video side as well as for still shots and if you want to film long periods out of a window on an aircraft also look for a good support that will attach to the window, to save you holding the camera for a long period.
I'm not going to suggest a individual camera as what one person may like is not to other's liking. You really need to make a list of all the usage criteria that is important to you and then look for cameras that fit the bill. Then armed with a shortlist, actually go to a camera shop and try out some of your short listed cameras to see how they feel and how intuitive they are to use.
One thing that I've always had to have on my digital cameras is a viewfinder [either digital or optical] as I've found trying to take shots outside in bright sunlight using a rear screen is a complete non-starter for me, as most [if not all] screens are virtually impossible to use in bright sunlight.
