This year's MAKS International Aviation and Space Salon, which took place on July 20-25 in Zhukovsky near Moscow, was unique. The pandemic and entry restrictions limited the presence of foreign nationals. The need to submit a vaccination certificate or a negative PCR test to enter the show further reduced the audience. Within six days, just 135,000 people visited the exhibition; two years ago, 579,000 attended. The flight displays, which are traditionally a strong point of MAKS, were also weaker this year.
