A great composite picture of flights leaving an airport.

Yeah, too bad the guy filched it from someone else by taking a photo of it at an exhibition and posted it to Flickr without credit. And now he’s taking credit for it as if he created it? Wrong. So wrong.

first last,
If you read the description, you would see that there were no labels up at the exhibition hence credit was not possible (like you, not leaving a name). He/she states it was taken at a show and never claimed credit as the creator.
You are wrong, so wrong. Learn to read.

Hey now, let\’s keep it polite. As James mentioned, the author posted in the comments:

thanks so much for dropping in, guys!
it was indeed the best work in the exhibition.
if only the labels were up.
sorry, er-minio, i wish i knew who the creator was, whoever he/she is, is totally brilliant and has a wicked sense of humour. i was at the opening until it closed at 8pm and the labels were still not up yet, sadly.

They look like models, since there are a number of aircraft represented there that would never actually fly into Hannover.
