Because it is the best experience on earth. Requires, skill dedication and planning which makes it an amazing personal challenge.
I am sat in the aeroclub at Barkerby outside Stockholm about to fly to Copenhagen and then onwards home. There are no less than 7 UK aircraft here including 3 microlights. Yesterday I was in Germany at Bremerharven.
Flew 598nm in 2:40 from Bremerhaven to Barkerby.
Flying is about pushing your boundaries and seeing the world under your own steam, not sanitized and packaged.
