(CNN) -- One by one, surviving family members and friends stepped up to a podium in Arlington National Cemetery. Before them were short lists of names, which included their loved ones -- fathers, sisters, sons and more. Slowly, they read the names, each one punctuated with a ring of a bell, to honor and remember who was lost. A quarter of a century ago Saturday, Pan Am Flight 103 exploded in the evening skies above Lockerbie, in Scotland, killing all 259 people on board and 11 more on the ground. Events Saturday in the United States and Britain marked the 25th anniversary of a bombing that devastated families on both sides of the Atlantic. It remains the deadliest act of terrorism on British soil.
