The video below shows several near mid-air collisions between UFOs and planes.
An unknown object crashed against an airplane from Aeromexico while it was flying near Cancun.
A Cesna airplane did a flight near Toluco. During the flight 5 objects approached the airplane. They were flying in the other direction and passed beside the plane.
A sphere passed near a Boeing 747 and a bright object was moving right towards another airplane. Another recording shows a UFO that was static in the sky while an airplane passing by.
The cases as mentioned above are just a few of the many near mid-air collisions which happen every year.
Other well known cases are: (See Article)

In many cases the objects are Drones, flying through restricted airspace, such as airport control zones.
As a result of these dangerous situations, the British Civil Aviation Authority (CAA) launched a “Dronecode” of conduct on Wednesday that drone users must follow, or face “prosecution and a possible jail term or fine.”
The CAA’s press release also noted that Drone manufacturers had started to program drones with “geo-fencing,” which can be used to stop unmanned vehicles from flying above a certain height or into restricted areas, according to a cnbc news report.
Despite that often Drones are the cause of near mid-air collisions there are well known cases of near misses between objects and planes which cannot be explained.
