Hello!
Just for comparison another airshow display which was low but in my humble opinion with more regards for safety than the A310 discussed here.
I was there that day. Nice to look at, but neither very low nor very spectecular and not dangerous at all. Nothing compared to what Airbus used to show with A300s and A310s at Le Bourget in the 80ies.
The airline has since changed its name to Germanwings.
No, it is still called Eurowings, but does not operate Airbusses any more (see
http://www.eurowings.de).
Greetings, Max
