Hart was badly hurt during a televised debate when former Vice-President Walter Mondale used a popular television commercial slogan to ridicule Hart's vague "New Ideas" platform. Turning to Hart on camera, Mondale said that whenever he heard Hart talk about his "New Ideas", he was reminded of the Wendy's fast-food slogan "Where's the beef?". The remark drew loud laughter and applause from the audience and caught Hart off-guard. Hart never fully recovered from Mondale's charge that his "New Ideas" were shallow and lacking in specifics. Earlier in the same Democratic primary debate, Hart committed a serious faux pas that largely went underreported. Asked what he would do if an unidentified airplane flew over the Iron Curtain from a Warsaw Pact nation, Hart replied that he would send up a United States Air Force plane and instruct them to determine whether or not it was an enemy plane by looking in the cockpit window to see if the pilots were wearing uniforms. Fellow candidate John Glenn, a former Marine Corps fighter pilot, replied that this was physically impossible.
