Survivors have said to find themselves amid mud/water outside the airplane already (didn't specify if still attached to their seats). One survivor speaks of relatives seated by her side and another ambigously accounted as "by her other side" (but could easily be in front, or across the aisle). She said her partner (or brother, I forget) was still by her side (another survivor if I recall correctly) but the other relative, when she went to "check on her" was not in the "right (relative) place" and actually she 'found someone else there' and couldn't find her relative nearby.
Remember virtually no large section of the airplane survived the impact and the fire just took care of whatever was left, but the airplane was already broken in many (actually way many) parts.
This wasn't exactly a large chunk of the plane seats that produced lots of survivors, but an area with relative few obstacles and much softer (and wet) ground where some of them ended up still in not-too-large chunks of fuselage. They say to have felt the shallow water and walk off/crawl off by themselves. One of them, an emergency rescue worker herself that happened to be a passenger in that flight, realized she had a broken femur when she tried to stand up twice after feeling water 'awoke her' and tried to help nearby victims, not very succesfully.
Once the in-flight recordings reach the judiciary system here in Spain, as it has been stated, if they are anywhere near "interesting" they will be leaked to press in all likeness in a short time. This country does not believe in "secret anything".
