Need Money, well done on passing the lanterns mate!
AdamLT, I'd be incline to agree with east_sider here. Don't be so quick to take the tests at gatwick....as failing them see's you getting logged as colour unsafe...and this will make things harder for you. There are plenty of lantern tests out there without leaving Europe. Do them. If you are as passionate as you say you are about your dream, you will do these tests. And hopefully, pass one.
Good luck.
