Crop Circle Connector had to place a notice on their site that aerial photography could not be credited to appropriate photographers. Here is the actual listing:

ENGLAND - Noted English crop circle-researcher Colin Andrews has claimed that the British Civil Aviation Authority [CAA] sent officials to mingle with the audience at a crop circle conference held in late July at Glastonbury. Seemingly,the officials were looking for people selling crop circle photos that had been taken from the air.
Andrews said that pilots who do not hold a commercial pilot's licence are reportedly not permitted to fly anybody who is engaged in a commercial act while in flight. This means that taking any crop circle photo from the air for commercial purposes is prohibited. According to Andrews, crop circle researchers who attend conferences and engage in selling such photos for sale in magazines, have been targeted to identify the local pilots who have been essential to crop circle research, past and present. Threatened with the loss of their licences, these pilots might now be forced to stop flying anyone over crop circles.
Official warnings have already gone out telling pilots not to engage in these flight. "This has created a very serious situation...for aerial work in England this year, and places future recording of crop circles in Great Britain in jeopardy,"
This complainant has probably noticed ( which angered him ) that newspapers and even the BBC have been showing other photographers images rather than his own. As we are aware that images do sell and bring in a substantial income but as other photographers use a cheaper form of flight such as microlight based aircraft rather than expensive helicopters then they can of course sell their images for less. In todays financial struggles even newspapers are probably seeking cheaper alternatives but there is a problem !. To take images from the air, especially if they are for monetary gain then one must use a pilot with a commercial license. The smaller airfields are regarded as flight schools and do not hold commercial licenses, so they can take you for a flight which can be regarded as a trial lesson and not a photographic session. As there has to be a flight log of every take off and landing, the regular names would keep on popping up time and time again, so the Civil Aviation would pick this up and suspect that trial lessons are not on the agenda but a photographic session would be ( hence connectors statement saying that no names are to be placed on images from now on, unless of course you use a commercial service ) - so that leaves the airfield in a dilemma. If the smaller airfields continue to provide a service such as a photo session rather than a trial lesson then they can lose their operating license. There are ways around it such as using an alias name on the flight log but that would be regarded as fraudulent and not recommended as any insurances to cover you in an event of an accident would become void ! - so do be cautious in what you do.
However if you own your own aircraft and are not tied to the airfields restrictions and you are not a pilot who is employed by the airfield then you can snap away as much as you want. There are always ways around showing you aerials of crop circles but as long as the images are not intended to be commercially sold. In theory any images taken by the regular photographers after the date when the complaint was raised, cannot be included in calendars etc., unless of course they use a commercially licensed pilot.
