Would like to get back to the issue raised earlier on about the access to the flightdeck and the rescue of the cockpit crew.
From photo material available it would seem reasonable to assmume that because of the impact the floor came up to a such an extent that this pushed the standing sills of the armoured flightdeck door came on both sides out through the top of the fuselage, leading the door to become stuck.
Early eyewitness report on Radio Noord Holland had said that the crew had been found slumped over the instrument panels in an obviously grave condition.
Pictures of the righthand side of the cockpit, where there is the only window which can be opened from the outside, show the release mechanism under the window (partly) extended. Independent whether this has been caused by the crash itself or manipulated by the rescue services, the bottom line is that the DV window remained unopened.
If the DV proved unopenable, it remains a question why, as the rescue operation progressed, the emergency services apparently saw it fit to start cutting substanitally in the fuselage in the fwd righthand side of the cabin (comprising two windows and the hull underneath, under the letter "H" in Turkish) and not apply the obviously present cutting gear to gain access to the flightdeck.
It has been said that access to the flightdeck would "disturb evidence" in the cockpit, but surely this cannot be put above attempts to save lives ? I won't state explicitly what I suspect is the reason for the initial absence (just after the crash) and later appearance (in the course of the rescue operation) of a white image in the cockpit just aft of the chart stuck in the right DV window. This image is of course no longer there on the second day.
There were reports later on in the rescue operation that an emergency worker had been seen on the cockpitroof. And indeed pictures taken the day after the crash, at the point where the flightcrew had been recovered from the flightdeck, show that the tear in the cockpitroof where the righthand side of the armoured door sill is sticking out has been substantially enlarged and the sill itself brought down and slightly forward in comparison with just after the crash.
Below links to some of the pictures to support these "constats".

Photo at stage where rescue operation is well underway. Cockpit roof still untouched. Rescuers looking into cockpit; White image aft of chart stuck in DV window. Why have they cut the hull in the fwd cabin section under the "H" of Turkish ?

Photo after access has been gained to flightdeck; clear that cockpit roof has been worked on: door sill has been moved and hull tear has been enlarged. Obviously no longer white image aft of chart stuck in DV window.
