Yesterday afternoon, Prince Louis and his older son, Prince Gabriel, attended the general assembly of the Fédération Aéronautique Luxembourgeoise. The event took place at the Centre Culturel in Beckerich. Prince Louis has been the patron of the Luxembourgish aeronautic federation since 2011. Even in non-royal patronage life, the Grand Duke's third son is very interested in the matter: While living in the United States a few years ago, Prince Louis
took courses in Aeronautics and Aeronautical Management and gained a
"Private pilot certificate".
