Boeing makes revised contract offer to engineering union

NEW YORK Jan 11 (Reuters) - Boeing Co said on Friday it made a revised offer to the union representing its 23,000 engineering employees, a move that comes the day federal regulators launched a review of the design and manufacturer of Boeing's 787 Dreamliner after a string of mechanical and electrical problems.

The two sides are meeting this week to renew a contract that expired in November. Federal mediators joined the talks in December after the talks appeared at an impasse.
