NEVER fly your drones under the bridge!!!

You should never fly along under the bridge through colonnades
as it has huge interference in RC signals,

You will lose
- GPS signal
- Screen Signal
- Navigation Error
- Control lost

and when signal is lost, it will automatically go into RTH mode, 
which will rise vertically, which will bump in to the bridge above, 
and end up crashing into the river!

Never, Never fly under the bridge, and fly the drone to the end of the bride like I did. 

Fly outside diagonally far from the bridge so you can catch the signals back and forth.
