I've asked this before and never got a satisfactory answer.
Why don't they have video cameras on the wingtips to help avoid such incidents?
With all the glass panels on the cockpits surely one could be switched to monitor the tips whilst taxying?
It could also be switched to cameras under the plane to monitor the wheels when away from other aircraft to avoid putting one on the grass or running over debris.
Even a handheld unit which could be stowed away when actually lined up on the runway would be less expensive than accidents.
I would imagine the cost of retrofitting video cameras (or even designing in on new planes) would outweigh the cost from these relatively rare events.
I would also question how effective the cameras would be at night (the accident above occurred at 9pm local)
