This is an abbreviated version of the article: Regional Aircraft-Makers Work On Future Concepts.
Remember the aviation boom times around the turn of the century, when it seemed almost anything would work in the fast-expanding economy? Those 50-seat regional jets, especially—airlines ordered almost 1,000 regional aircraft in the year 2000 alone. And in 2007, a few years after the introduction of larger regional jets such as the Embraer 170/190, the manufacturers collected orders for another 750.
Today, the industry could not look more different. The entire commercial aviation sector recorded only 53 orders in 2020, largely due to the effect of the coronavirus pandemic. Total orders stood only at 310 aircraft in 2019, but 110 of them were for Comac aircraft and placed by state-owned Chinese airlines.
