Occurred on November 20, 2017 / Concepción, Biobío, Chile - It was filmed by a passenger who uploaded it to the internet with the title  ‘Should I be concerned?’  The footage shows that he was able to pull the frame right out.

Should I Be Concerned Or ?

NO CAUSE FOR ALARM.
What he is prying on is the inner window reveal, a cosmetic piece attached to the cabin sidewall. there is a failure of the adhesive holding the window reveal to the cabin sidewall, that's all.
THIS IS NOT A STRUCTURAL PART OF THE FUSELAGE.
If this was the pressure window in the fuselage he would not be able to pull on it as at altitude there is 8 psi pushing against the window, which is pushing against the skin of the fuselage.

One part of an aircraft’s window design that has always baffled passengers is why there is a small hole in them.

It is not the window which has a hole it's the scratch panel.Equalises pressure & stops condensation.

thaiga, as hogman said, this is for pressure equalisation, this is in the pressure window, not the one on the cabin sidewall that the passenger is playing with.
It is a 2 pane matrix, similar to double glazing in home windows in Canada. But as there are pressure drops and increases as the aircraft goes through a flight cycle, take-off climb to altitude and landing, if the hole was not there the double pane would burst at altitude with the increased pressure in between the panes.

If said passenger was able to mess with the pressure window then there would be a loud bang as he would get a quick trip to an unknown destination from 40,000ft. But this would take some serious grunt to overcome the 8 psi differential between the inside of the aircraft and the outside at 40,000.

thanks for the explanation KC,hogmam, (If the passenger was able to mess with the pressure window) he would of got sucked off  ::)
 (no pun intended)

cabin design integrator Bombardier Aerospace, very interesting.

Unfortunately I did not work on the C Series aircraft, but I know the folks who did and they gave them a very long list of items to upgrade from the Regional jet that I worked on. Sam is an import from the Belfast division where they make the wings for the "C", his reference for the double bubble type fuse is back to the De Havilland Canada dash 8 series. But the design group have done a tremendous job on the whole aircraft, if you look at what they have done with the cockpit, more vids on Utube, it was designed with Boeing and Airbus pilots in mind so that the transition for either one to the "C" would be very easy. The cockpit has been labeled a pilots cockpit.
I started with BA at the start of the CRJ 100 series  50 passenger regional jet,the first commercial aircraft for Bombardier, the design was initially started under the old Canadair company,but that's another story. I retired just as the new "C" was getting underway and I was even approached later as they had a shortage of Project Engineers, but is was too comfortable living in Thailand to get back into the rat race again.

Thanks for that KC. very interesting. gone are the days of Dan Air which was my first flight many years ago.
