I am flying to Billund Airport. It was opened in 1964 and there was no terminal so all passengers had to wait underneath a lego hanger that was made by the founder of Lego (Godtfred Kirk Christiansen) .
Billund Airport was then built around this mans private airfield!
a interesting historical blog about the airport and lego – here
and the wikipedia page for Godtfred Kirk Christiansen (the founder of Lego) here
