as a previous member pointed out risk is perceived differently by different people, if you were watching from the cafe, it looks low risk, but if you owned one of the parked aircraft it was pointing at it would be high risk!
as the previous posts have shown, ground accidents happen and will continue to do so, but we have to reduce risk otherwise insurance costs will continue to rise for us all.
