In trying to be that bit more creative I have the following image in the queue. I personally think the spray from the Baby adds drama to the image, and I'm sure this shot wouldn't get a rejection for it. I do however have another shot taken seconds after where the CRJ is shrouded in a fine mist as, in the background, the 737 roars into the air, leaving a huge trail of spray behind. I haven't got the shot handy but I would imagine this kind of motive (it almost looks like fog!) would be unacceptable, however the reason for the upload is clear with the 737 behind rotating.
A go-go or perhaps a no-no?
