I was quite surprised about one (all?) of doors on my latest Air Berlin flight. In particular:
- the "Door locking indicator" was empty (black),
- the "Cabin pressurized" light was not lighten and
- the "Remove before flight" red strip was not removed.
(I am the owner of this picture and I authorize anyone to use it for any purpose except illegal activity.)
The plane landed safely and there was no noticeable in-flight change of air flow/pressure etc. Still, I wonder if the described situation is a violation of some in-flight procedures or at least odd in any way?
