It only took 18 months from our first episode for #nerdbird Mark to finally appear for his intro with our now-vintage lightning round questions! Unlike the founding #nerdbirds, Mark was not on the Virgin America final flight in 2018 and brings different perspectives on aviation, including his time at Boeing and decades-long loyalty to Delta (not to mention the decade of roadtrips with co-host Rachel). This is also our first live episode at an airport, so enjoy the background sound effects.
