The 2021 Dubai Air Show is a test of the new normal and the first large-scale civil international air show since COVID-19 ravaged aviation. Yet, Dubai is set against the backdrop of a world that is not as flat as it used to be. Freight has kept the civil aviation business alive through the pandemic. The A350 is set for launch here, the 777XF is coming, too, but not yet. Russia’s MC-21 is making its debut in Dubai. It’s a project that represents the geopolitical tension disrupting once open east-west supply lines, but its biggest opportunity may be at home where domestic air travel is booming again.
