A former commercial pilot in Texas faces up to 20 years in prison in a child pornography case involving millions of images.

Federal prosecutors in Houston say 47-year-old Todd Steven Ewanko of Humble pleaded guilty Monday to distribution and possession of child pornography. Sentencing has been set for May 7.

Ewanko formerly was a captain with Colgan Air Inc., doing business as Continental Connection. He was suspended following his July 2010 arrest and has remained in custody.

Officers who searched Ewanko's home seized several computers. Prosecutors say the equipment yielded millions of images and videos related to child pornography.
