How did authorities find out about this?

Surely it was not the pilot who told them about this.

Olympus Mju 770SW

This camera has a major problem at 3X optical zoom it produces very grainy images. I tried using different ISO settings but no help. With no zoom images look reasonable but as soon as you zoom in they become grainy.

Similar experience

I had similar experience back in Ukraine when going on a trolleybus (electric powered bus). Its pantograph got unwired in a 'neutral zone' in a middle of intersection. At first driver was uncertain about what to do but then another driver from a passing trolleybus recommended to ask passengers to push it a couple of feet. Small effort from 10 people and we were ‘on the road’ again.

And at the same time ...
