The FBI states this type of surveillance plane is being used to weed out criminals and problematic people in society - But is it? These small civilian spy aircraft have now been around for about 6 years. And as time passed in those 6 years - so has the objective in what the planes are being used for. I believe it is not only for gathering data from cell phones - but more for keeping an eye on a targeted person who is believed to be some sort of threat. Only they aren't..
There is a huge chance that these aircraft can in fact do many other things that can harm the subject or subjects the pilot or corporations or FBI are hell bent on hunting from the air. This is only my opinion and my belief - but things have a way of connecting themselves in life. And so do patterns of activity.
If you want to know if a plane is flying over your house to collect data - keep a watch for it. Normally these planes will keep coming back. In fact, the same plane - over and over and over again. Every 10 minutes sometimes. And at night - normally at the same exact time. For months and even years at a time. It is a job to the pilot and he will most likely fly until he is told not to.
