ARLINGTON, Virginia, Oct 28 (Reuters) - Hundreds of U.S.

air traffic controllers have taken temporary second jobs as they

miss their first full pay check on Tuesday, putting more

pressure on the strained aviation safety system, a union

official said Tuesday.

National Air Traffic Controllers Association President Nick

Daniels told reporters at Reagan Washington National Airport

that the number would rise as more controllers look for ways to

pay bills.

"It's quickly going to be 1,000," Daniels said, calling on

the government to end the standoff. "We want the shutdown to end

today... Whatever way that it gets done, that's what the

American people deserve."
