The accident description of the Binter canarias flight sayd a passenger noticed that the left engine stop just before the crash.
Now, if you look closely at the elevator thingys (hehe sorry i can't remember the name) you can clearly see smoke trails over BOTH sides, could this mean there was a double engine failure? I'm sure that it cannot be normal because if ti is we've found the source of global warming!
Unfortunately i cannot put the pictures on due to copyrights but here is the link to the page: http://aviation-safety.net/database/2001/010829-0.htm
Please tell if you have also noticed it or if the investigators have!
