Dutch - I think it inappropriate to discuss too much about this, but I would assume that following the enormous impact and deformation of the cockpit area it was judged that time would be better spent on access to the injured passengers. From what I have read, any sort of practical medical treatment of the crew would have been near impossible via the DV window, if indeed it had been openable.
The cutting under the 'H' may well have been the only access in the deformed structure to some of the business class seats?
