NEW: Jared Isaacman was recently joined in the cockpit by @SecDuffy, who Trump just named interim NASA Administrator, as they lit up the skies together at EAA AirVenture Oshkosh in an MiG-29. Both men are aviation enthusiasts: Duffy is currently serving as the 20th Secretary of Transportation, and Isaacman founded Draken International and built the largest private fleet of fighter jets in the world. The two just made a surprise appearance at Oshkosh, the world’s largest aviation event, which this year drew more than 700,000 attendees and over 10,000 aircraft.
