I'm too lazy to translate it myself, so here is the Google version - There is a so-called inspection door that sits outside of the fuselage behind the left wing, said Lars Christoffersen, accident inspector from AIB to Nordvestnyt.dk
The door provides access to the aircraft's hydraulic system C, and the loss of the result, according to Lars Christoffersen, no danger to passengers.
- The door has a total of eight locks, so we have no idea how it could break loose, "says Lars Christoffersen Ritzau.
He describes the door weight as "not exceeding 20 kg." It was located behind the left wing, where - until it was turned into a free floating air missile - protected aircraft's hydraulic system for wind and weather.

Quoting chrisair (Reply 7): It won't be falling that fast. It'll hit terminal velocity well before it reaches 900 km/h. I think it's somewhere around ~18 m/s using the 10 lb door. Even 20 kg it's only ~38 m/s, or 85 mph.
If my complex calculations are correct if the door was doing "only" 85mph instead of 900km/hr when it hit me on the ground the result is likely to be the same......death. One death would simply be a fraction of a second slower than the other.

Quoting LAXtoATL (Reply 2):
Probably should clarify in thread title what type of door. I assumed a pax boarding door flew off in flight!
This would more appropriately be labeled an external access panel.
same, I thought It was a passenger door, that would be terrifying for the passengers...and who knows what will it hit on the ground..

My first post in this forum.
The incident happened on 20 November this year where N722TW was flying DL118 (JFK to CPH). At the time of the incident the plane was descending towards CPH flying around 10000 feet. The plane landed safely in CPH and it was here the missing piece was discovered. The plane was flown back to JFK 2 days later as DL9934.
Thats awfully heavy for an access door. They are usually composite these days and are very light (especially if 8 hartwell latches secure it)...an alloy over wing emergency exit is far more substantial and barely makes 50 lbs. It really is nothing more than a streamlining fairing. It would just flutter down to earth like a giant leaf.

Quoting adxmatt (Reply 15):
The pilot probably never even knew he lost it until after landing and ground staff asks what heppened.
Quoting AY-MD11 (Reply 22):
hmm... How did they know that it drop at 4000 meters?
Quoting flyingalex (Reply 23): Since they found the missing part, it's fairly easy to estimate the altitude from the location of the village in which the door landed. When passing X, the plane should be at Y feet.
There are some reports saying the loss of the door resulted in a hydraulic problem which was shown to the pilots in the cockpit.
: what airline is flying JFK-CPH in a 757??? i know of 757's doing trans-atlantic, but i didn't know they penetrated that far into europe.
: Why? it's a door so what difference does it make what door....other than a feelgood factor on a.net? Well, someone's wrong somewhere. It's 20Kgs in t
: When I was talking about skydiving, it's because I'm practicing it. We jump at 4000m and terminal velocity in a "banana" position is around 200Km/h. I
: This is apparently approximately where the door fell off: (from bt.dk) Seems like the door hasn't been found yet.
