Yes the flash reflection is a problem, but even cloning out the flash would still leave you with dark screens which frankly, makes for a very unattractive picture. Given that we have many, many cockpit shots of the more common types I would seriously question whether there is any point to uploading shots without the screens actually displaying something.
Its badmotiv for reasons of the reflections - you can't clone out the reflections because we've seen the picture now and if we see it again with no reflections we will reject it again because you're not allows to manipulate photos in that way. If you don't like the decision, appeal.
There are old pilots and there are bold pilots, but there are no old bold pilots
