The Paris Airshow has been cancelled for the first time since World War Two, raising questions about the speed of the aerospace industry's recovery from the COVID-19 crisis.
Organisers said that Europe's largest industrial showcase, which attracts over 300,000 people every other June in alternation with Britain's Farnborough Airshow, will not go ahead next year because of the coronavirus pandemic's "unprecedented impact" on aerospace.
Aviation experts said that the early cancellation reflects the high advance costs of the event, which is estimated to generate total spending by exhibitors and attendees of $1 billion, including $400 million on building, temporary hires and security alone.
Scrapping the 2021 show also deprives the industry of a deadline to stimulate deals and focus attention on new products.
"The Paris Airshow could and should have been a catalyst for recovery. The organisers have clearly listened to the big exhibitors and decided it was not worth the risk," said veteran analyst Howard Wheeldon, who has attended dozens of air shows.
"The bigger worry is that this is saying that confidence won't be returning soon, not only in aviation but also in the wider post-COVID world," he added.
The biennial jamboree traces its roots back to 1908 and had previously only been cancelled during the twentieth century's two world wars.
The last edition at Le Bourget outside of Paris generated contract announcements worth $140 billion.
Airbus And Boeing
Dominated by the duel for jetliner orders between Airbus and Boeing, the seven-day extravaganza had already become a tamer affair as demand peaked and a breed of cost-conscious executives less interested in the PR drumbeat entered industry boardrooms.
But the 2021 show was emerging as a barometer for fragile demand, especially as Boeing seeks to relaunch its 737 MAX.
In one of the most dramatic air show coups of recent years, the planemaker unveiled a tentative 200-plane rescue order for the troubled MAX at the last event in 2019, but the fate of that order now looks uncertain as the coronavirus rips up growth plans.
Airbus, which dates back to a Franco-German co-operation deal that was signed at the show in 1969 and which has made a practice of drumming up suspense over orders from Gulf and low-cost carriers, said that cancelling was "difficult...but responsible".
