Today on Dakota Midday, host Paul Guggenheimer talks with Miles O'Brien, correspondent for tonight's Frontline documentary "Flying Cheap." It's about regional airlines that fly under contract for the big airline companies, but they don't have the same safety standards. Then Guggenheimer welcomes David Volk of South Dakotans for Lifesaving Cures, a group supporting embryonic stem cell research. State lawmakers recently rejected a measure dealing with embryonic stem cell treatments.
