So nothing prevents one using gendec.eu to generate a UK GAR form for a flight Shoreham to Alderney?
I think we’ve done this before but gendec.eu is a dead URL. They have their server poorly set up. You have to use at least www.gendec.eu, and probably the fashionable civil-liberties-safeguarding form is https://www.gendec.eu/
How do they plan to make money?
