Guys Guys... Nose wheel is smaller than other wheels and it takes too much load during running before take off. Easily a jackal or a brick can cause it to disorient and skid and eventually brake. This is absolutely possible and don't try to mock the situation. If there are stray dogs out there, it is the responsibility of the people, not the government. If you see a dog give birth to many pups, and you dont want them, its your duty to call the corporation of your locality to take care of the pups or call blue cross and they will deal with it. Else they grow up and find their way into runways and almost kill people. You dont see these kinds of accidents in western countries, because they do what i just mentioned. So wise up friends and do the right thing.
