The young flight attendant started gathering airplane spoons 13 years ago, after going on a holiday in Spain, with his sister Gunda. While they were flying towards their destination, she suggested they take one of the spoons, as it may prove useful on their vacation. After returning home, he ended up with the spoon, and every time he used it, it reminded him of his nice time in Spain. From there on he decided to collect as many airline spoons as possible, and he stayed true to his goal.
Dietrich says his family and friends have been very supportive and have added to it every time they got the opportunity. He is now the proud owner of 1,760 different airline spoons, some dating back to the 1920s and 1930s, when companies like Pan Am were still around. While some of his spoons are of unknown origin, he relies on the Internet to solve the mystery of his collectibles.
