UAVs are not permitted into the database. This issue has long been a hot topic of debate within the crew, with some UAVs closely resembling conventional aircraft while others are more akin to radio-controlled scale models or even guided missiles.
In order to draw a very clear line in the sand and remove any ambiguity, the rule is that no UAVs
are allowed to enter the database.
Having discussed with Johan, we cannot recall exactly what date this decision became policy. Therefore all existing images should remain. As always, photos are judged by the contemporary standards at the time of screening. Quite obviously it would be unfair to retrospectively apply a rule to previously accepted images. Only in absolutely exceptional circumstances are images retrospectively judged (if they cause significant offence, etc). This is not such a situation.
So, in summary, those in the db will stay. No further UAVs will be accepted. If you notice one which sneaked into the db by mistake, just email the screeners and we'll take care of that. We're not always perfect!
