I can confirm that Google uses a combination of air and satellite imagery. There are several incidents that
The Register calls "cloaking devices", where one tile may contain part of a plane or train, and the neighbouring tile does not, leading to a 'cloaking' or 'decloaking' of said vehicle.
So yes, the tiles at Stansted can display such similar occurrences. While the planes at the north-eastern most end of the runway might be queuing, but the 'two' planes exiting the runway must be the same plane.
The photo of the Easyjet on approach is definitely a different series.
