that wouldnt happen to be a very large LH only airline based out of LHR would it??? I think not letting crew open the doors on a day to day basis is crazy!! Because in an emergency it'll be important that you can feel how the door operates and how heavy some are! In my last airline based at LHR we could not open the door from the outside. only flight crew or engineers were allowed. But in my most recent airline they didnt mind as long as we made sure the door was not armed!!! (737)
