JEFFERSON CITY, Mo. (AP) - Missouri senators have passed legislation offering up to $1.7 billion of incentives over two decades for Boeing to assemble a commercial airplane in St. Louis. Senators passed the bill 23-8 Wednesday while meeting in a special session called by Gov. Jay Nixon. It now goes to the House. Missouri is one of more than a dozen locations invited by Boeing to bid on assembling the new 777X airplane. Most other states are crafting their proposals privately. But Nixon called a special session because he wanted to offer more incentives than currently allowed under state law. Under Missouri's plan, the amount of incentives Boeing gets would depend on the number of jobs created. Supporters say the Boeing project includes 2,000 to 8,000 company jobs, plus thousands of more at its suppliers.So far, Alabama and Kansas are also working to land the new Boeing contract.
