The "hanging thing" is the r/h gear alternate anti-skid module.
A pretty good whack to punch this off its mounting plus the 4 hydraulic tubes that are fitted to it plus upper wing panel. A large chunk of rubber going pretty well straight up from #8 wheel must've done the damage. You can see the wheel minus it's tyre in one of the photos. Alternate braking is from centre hydraulics so centre fluid would have been lost when module was hit. Thus the alternate gear extension as ext/ret is powered from centre system.
