British Airways plane is struck by drone as it prepares to land at Heathrow | Daily Mail Online (http://www.dailymail.co.uk/news/article-3544651/British-Airways-plane-struck-drone-prepares-land-Heathrow.html)

It was only a matter of time ...

Don't believe everything (or anything) you read in the Mail. There is zero evidence that this was in fact a drone. The whole situation - the altitude, primarily - makes a drone rather unlikely. Current speculation is that it was a plastic bag.
