The CAA should find the pilot responsible and throw the book at him. Maximum sentence, f**k his life up, loose job, loose house, loose family (if train spotters have families). F**k one person up so that hopefully others will think twice before being twats with multi-rotor camera platforms. Also might save a serious incident when many innocent people might have their lives upset by the action of one idiot with a 'drone'.
Where's the 'F**k 'em up' icon?
