Hilarious! Is that why it is marked in red? How many times has somewone worried about this 'loose, flapping thing' on the belly? Work on or around airplanes: know them. And yes, if you see something that is obviously not right - not marked in RED as normal, speak up. Ground staff too need some functional brain power - and proper training. (Best example is that 'little bump.' Grounders are NOT supposed to bump birds, but it happens. For the sake of 3 or 300+ souls, when - not if - that 'Little Bump' happens, tell someone. Please.
