Oct 2 (Reuters) - U.S. Senator Bernie Sanders urged

Boeing ( BA ) in a letter sent on Wednesday to end the

eight-week-long strike in the St. Louis area, where it produces

fighters, munitions and other military aircraft.

"Do the right thing," Sanders said in his letter to Boeing ( BA )

CEO Kelly Ortberg.

The letter was sent the same day Sanders and other senators

used a Senate committee nomination review hearing to slam

Boeing's ( BA ) behavior during the strike.

About 3,200 members of the International Association of

Machinists and Aerospace Workers District 837 went on strike

on August 4.
