I agree with Whale. In Transport Category jets, prior to V1, you can stop. After V1, you go. Period. Especially in Heavy jets. If you begin to deviate from SOP with a crew, it is going to cause confusion and a lack of coordinated action in the cockpit. There are very few things that are going to bring a Heavy jet down if you decide to keep going after V1, get airborne, clean it up, deal with it, and come back around and land in an orderly fashion. I'm glad no one was injured, but I'm really scratching my head over why they waited so long after V1 to decide to stop, then when they did, they didn't deploy the reversers or spoilers? (And yes, I know that accel/stop is not predicated on use of reversers. But obviously you want everything going for you that you can.) There isn't a lot of room for overrun at EBBR on any runway. They had to know they would go off the end and in the ditch...
