Passengers said the cabin seemed "noisier and colder than they were used to." That's when a crew member noticed a window seal flapping at the back of the aircraft.
A U.S.-bound plane took off from London last month with four damaged window panes, including two that were completely missing, according to U.K. air accident investigators.
No one was injured by the window malfunctions, which appear to have been caused by high-power lights used in a film shoot, the U.K.’s Air Accident Investigation Branch reported in a special bulletin published Nov. 4.
"The lights, which were intended to give the illusion of a sunrise, were placed about 20 to 30 feet from the aircraft, shining on first the right, then the left side of the craft for over nine hours in total.
A foam liner had melted away from at least one of the windows and several window panes appeared to have been warped by the thermal heat. "
I’m surprised by that, because I’m having a hard time picturing a setup that was all that much hotter than, say, sitting on the tarmac in Phoenix in the summer.
Am I missing something or is the term "thermal heat" just stupid? Are they trying to sound? Or is there some other meaning of heat that I'm unaware of and that would make sense in this context and therefore the description is needed?
Huh, to be honest, when i read this, it didn't connect with me how the lights made window panes disappear. were the window panes missing before the flight? It doesn't seem like the window panes fell on anyone or nearby property.
It's likely the crew was using fresnel lights which are bright and very hot. You can easily burn yourself or set fire to delicate objects after prolonged use. Not impossible to imagine a crew member moving the lights, leaving them on and highly focused to imitate a distant light source; like a magnifying glass under the sun.
The missing windows weren’t discovered until the plane was climbing at an altitude of 13,000 feet, according to the AAIB report.
“Several passengers recalled that after takeoff the aircraft cabin seemed noisier and colder than they were used to,” investigators wrote. A crew member walked towards the back of the aircraft, where he spotted a window seal flapping on the left side of the aircraft.
Wait wouldn't there also be a lot more pressure that you would feel from the suction of the missing window or would that only be felt by people at the back of the plane?
From the photo it looks like the inner window panes were still intact. That would be enough to keep the plane pressurised, I'm guessing. For a while at least.
Those windows are really thin plastic and are supported by the plastic trim and panels on the aircraft interior. They are highly unlikely to support much pressurization. Air would have escaped around them via under the panels and through panel seams.
Not really. Most planes leak quite a bit anyway- they’re constantly running air compressors to keep it at about the equivalent pressure of 6,000-8,000 feet.
At that point, it was merely mildly concerning. If the window had blown out mid-Atlantic that would have been terrifying- flying low enough to maintain pressure would expend too much fuel, etc. but they were only 10-15 minutes into the flight; so, no big deal.
Also? At 20kft, yiu have about 30 minutes before you pass out. (Airlines typically have 10-15 minutes oxygen reserves, for a fully packed aircraft, more than enough time to dive down to breathable pressures. Even from the normal cruising altitudes of 30-40k ft)
I’m surprised there wasn’t a flashy warning thing, though. At 14k-ish pressure altitude… the oxy masks should have dropped automatically
I would comfortably say that I would be at least slightly terrified if I were on that plane, regardless of how ultimately justified it would be. Nobody wants to hear that there is a problem or needing to turn back after takeoff.
