4 Begin 500-Mile Run in London to Mark Pan Am Crash

LONDON — Four people began a 500-mile run to Lockerbie on Tuesday to memorialize the 270 people who died last December when a Pan Am jumbo jet was destroyed by a bomb and crashed into the small Scottish town.

The runners left from outside Parliament in central London and are expected to arrive in Lockerbie on Sunday.

“They are all in good spirits despite experiencing cold weather, wind and rain. No doubt there will be snow on the route further north,” said team spokeswoman Shirley Price.

The runners are Tom Grace, 40, a songwriter from Brooklyn, N.Y., Yves Pool, 35, a French circus clown now based in the United States, Eleanor Adams, 41, an English mother of three, and Malcolm Campbell, a 55-year-old Scottish grandfather.
