Engine trouble forced a Delta Airlines charter flight carrying more than 100 military troops to Indianapolis from Fort Hood, Texas, to make an unplanned landing in St. Louis.

The airline calls it a  precautionary landing at Lambert-St. Louis International Airport at 4:10 Saturday morning.

Airport spokesman Jeff Lea says the airport deployed emergency equipment, but the plane landed without incident.

Then at about noon Saturday, a Delta flight from Atlanta made an emergency landing in St. Louis after a passenger smelled smoke in the cabin.  Again, no one was injured.

For both flights, Delta sent replacement planes to finish the travelers’ trips.
