I'm from Holland. After a lot of searching I came to skywaytesting.com Ordering the fit-to-fly test was easy. The advice to install the app could not work because as a Dutch person I cannot install apps if they have not been released (by skywaytesting.com) for foreign mobile phones. That was quite disappointing. I had to ask someone else to download and install that app. And help me process all the steps in an easy way. I didn't like that. The results came quickly (after about 1 hour), which was a stroke of luck. I hope and expect that skywaytesting.com will open up the use of the app to foreigners.
