pbr A commuter has described how one of the 77 bombers boarded her bus carrying a heavy backpack, looking nervous and sweaty.br ppbr Anita Dybek-Echtermeyer was struck by the "bad manners" of an Asian man who got on a crowded number 91 bus at King's Cross station in London on July 7, 2005.br ppbr He blocked the way with his large pack and knocked against other passengers, the inquest for the 52 victims of the attacks heard.br ppbr Ms Dybek-Echtermeyer later realised that the man was suicide bomber Hasib Hussain, 18, who killed 13 people when he blew himself up on another London bus in Tavistock Square.br ppbr Describing Hussain as looking "nervous and exhausted", she said his rucksack "looked very heavy and very properly packed - full, I think around 60 litres".br ppbr She added: "It had to be heavy because he had a strap on to carry the whole thing. Also, he himself looked very exhausted and he was sweating on his chin, and that was horrible to look at."br ppbr The mother of Anthony Fatayi-Williams, a 26-year-old oil executive killed in the bombings, spoke of the "yawning vacuum" left by her son's death.br ppbr She said: "Anthony's life was cut short in a needless, totally unnecessary and preventable attack on London.br ppbr "His family continues to miss him sorely, even after these five years. We, his parents, continue to wonder if his death could have been prevented, or even the attacks foreseen by the relevant authorities.
