nd looking back on his 1972 Senate campaign, he told Pennsylvania delegates at the Democratic convention that people from his hometown of Scranton, Pa., piled in up to 10 buses and drove to Wilmington, Del., to show him support. "Literally," he said, "there were hundreds of thousands of people."

THE HELICOPTER SPIN

In a Baltimore speech last week, Biden said: "If you want to know where Al Qaeda lives, you want to know where (Usama) bin Laden is, come back to Afghanistan with me. Come back to the area where my helicopter was forced down with a three-star general and three senators at 10,500 feet in the middle of those mountains. I can tell you where they are."

Two days later, in Cincinnati, he said Al Qaeda has re-established a safe haven and it's not in Baghdad. "It's in the mountains between Afghanistan and Pakistan," he said, "where my helicopter was recently forced down."

At a Sept. 9, fundraiser, Biden addressed his national security credentials by talking about "the superhighway of terror between Pakistan and Afghanistan where my helicopter was forced down. John McCain wants to know where bin Laden and the gates of Hell are? I can tell him where. That's where Al Qaida is. That's where bin Laden is."

THE FACTS: In February, Biden and fellow senators John Kerry and Chuck Hagel were flying in a helicopter over Afghanistan in a fact-finding trip when a snowstorm closed in.

"It went pretty blind, pretty fast and we were around some pretty dangerous ridges," Kerry told The Associated Press afterward. "So the pilot exercised his judgment that we were better off putting down there, and we all agreed."

He said the group waited for about three hours until a convoy with U.S. troops took them to Bagram Air Base.

"We sat up there and traded stories," Kerry joked. "We were going to send Biden out to fight the Taliban with snowballs, but we didn't have to do it."

He added: "Other than getting a little cold, it was fine."

The area was reported as not being under Taliban control. But Wade noted "it's the wild west out there" and the senators were transported under guard and with air cover from an F-16.

Though Biden never said his helicopter was shot at in Afghanistan, last year he asserted that he was "shot at" in Iraq. He amended that later, saying the quarters he was staying in while visiting Baghdad's protected Green Zone shook from a nearby blast, and "I was near where a shot landed."
