Airline pilots and cabin crew across Europe are holding demonstrations today to protest over rules governing their flying hours. They say the rules are putting the lives of passengers at risk. The protesters are demanding that European Union rules on flying times are brought into line with scientific evidence. A study report mandated by the EU in September 2008 recommends that an airline crew should not operate for more than 13 hours during the day and 10 hours at night. Current EU rules stipulate pilots work up to a maximum of 14 hours during the day and nearly 12 hours at night. Hundreds of protesters are attending events taking place at 22 airports across Europe. They say all they are trying to do at this stage is raise public's awareness and not to get in anyone's way.
