hi there .i just got back from gran canaria on monday night but it was some flight. we hit really bad turbulence and had the seat belt signs on for at least one and a half hours. and the captain(Ian) told us that he could not climb out of it as he had contacted the control tower.so although i was very nervous i remembered someone posting a thread about the pilot not being too much bothered by it unless his tea was spilt on his crossword..(when i had asked about turbulence )..so this did help me a lot so thanks again for the advice..
