UFO? Need help uploading/cutting

Ok, so I was recording shooting hoops so I can later try to make it slow motion and see it go in, but im new to it and Im just beginning how to do special effects and videos.
This is the thing, while I was shooting hoops 3 things went by the sky and they were fast, they disappeared in like half a second...but it happens 3 times.

I dont know what they were but I thought I should show you guys if you wanted to see it.
The problem is is that I want to cut out part of the video that I dont want people to see, I just want to show you guys the parts with the UFO(?), how is it that I can do this?

It is going to depend on what format your camcorder records in but most modern camcorders come with a free editing software (usually on a CD included in the packaging) that you can install for just that purpose. Also Most Windows installs have media editing tools which can handle the most common formats.

Ok, I got it ready. I just need to upload it, but they are kinda hard to see.
