here's the whole thing (I was editing as you posted
)
The first officer advised ATC that the captain was complaining about stomach pain and subsequently became incapacitated. An fully licensed off-duty pilot of another airline assisted the first officer by taking over radio communication, while the first officer returned the aircraft to Las Vegas and the captain was treated in the back of the cabin. The aircraft landed safely on Las Vegas runway 26R about 65 minutes after departure.
The airline reported the aircraft returned to Las Vegas when one of the pilots needed medical attention. A licensed pilot from another airline with full credentials assisted with radio communication. A replacement crew operated the aircraft to Columbus.
