or is someone going to tell me that is the wrong way to look at it?
helipad markings are excellent and, if used correctly, guarantee safe separation from other aircraft so going hard over to remove them would be a retrograde step.
The main issue with this accident was the pilot not recognising that the other aircraft wasn't positioned on the normal spot and adjusting her landing position to cater for it.
Whatever the cause of her not taking appropriate action (distraction, stress, complacency etc) the markings on the ground only represent one layer of safety you are still heavily reliant on the skill and actions of the pilot to prevent such a crash.
