Why doesn’t the race committee use a gun for the sound signals/ Well the answer is simple and complicated.
The Austrian juror should have his two staring guns with and did not appear yesterday. Panic in the organization. Phone calls where made to locate the wising person. After a while Helmut Czasny was on the phone but not very clear about what had happened. Our own juror Eline Moerenhout couldn’t believe her ears when she found out what the true story was. Helmut took the train from his home town to Rotterdam and was carrying the two staring guns in his suitcase. At the German border the police came on board of the train and arrested him for possible terrorism. Helmut forgot to bring his license and was thrown in a German jail. After a debate of several hours he was released and send back to Austria. He couldn’t get the guns to the race in time but arrived just in time to do his job at our event. The race committee is looking for policeman who like a day at sea shooting in the air.
