World's biggest airplane takes flight for first time over Mojave desert

The 500,000-pound Stratolaunch jet took off for the first time ever for a two-hour flight over California's Mojave desert. It's designed as a flying launch pad for as many as three satellite-laden rockets. CBS News space consultant Bill Harwood joins CBSN to explain why this launch is a benefit to the U.S. in the ongoing space race.
