Flying under bridges
Just out of curiousity, this kind of situations probably have created commotions before, but....
In France I was told that one of the reasons min alt was increased from 150" to 500" was to avoid flying under bridges.
So apparantly it is dangereous/undesirable.
But in France they make you fly 150" over mediterean p.ex around Cannes and Nice to be clear of traffic. In LAX you can see the dolfins and the baywatch girls around venise beach if at 150" you pass below LAX take-off.
In UK the Thames is considered a safe passage to London Heliport.
Am i wrong to suggest that in the precise case of the picture, with adapted speed (I do not want to generalise) it appears to be at least as safe below as above the bridge....
What is the catch....
In Belgium min alt is still 150", so flying under some bridges would be technically possible.
