On second watching of the video I noticed there was also a plane in the video. I was looking so longingly at the summer terrain I hadn't noticed it. It is a lovely aircraft also.
That's really quite convincing. From the lighting to the audio and the "camera work" it only needs a slight squint to make you believe this is real footage.
However, I must ask, what is that weird chirrup sound that repeats throughout? It reminded me of a DJ scratching vinyl.
