What software do you have?
If you are on windows you should have some version of Movie Maker.
It is pretty much click and drag - check out the help files or online tuts.
If I was doing this I'd find a soundtrack first. Something that is tagged: driving, action, high tempo etc.
When you hear it you'll know it is right.
From there throw the video into the app and add in some choice photos of what you are selling.
Start editing - cut smaller clips from the video - don't run the whole thing end to end.
Cut in and out of the photos between the flight clips.
Use straight cuts for most of the transitions, if you have to use transition effects keep them simple and short - don't use too many different effects.
There should be some kind of pan/crop effects available for the photos so they don't sit there static - again simple is better - unless you are doing a Monster Truck Weekend or Miley Cyrus video.
Get it looking the way you want and add the titles last - if you think you need them.....
You can find some music here that you should be able to use (I think):
