and another group Riga - BTI6RZ - this was very loud - i think it has a broken exhaust pipe ... Stavanger - KLM67K - no so loud, but enough to bother you ... very important destination. you must have multiple flights per day to Stavanger. its the London of the North ... honestly I hope schiphol and klm will get what they deserve otherwise this world doesn't make any sense and it should end faster.
