Over 70 companies refused to participate in the Singapore Air Show due to concerns about the outbreak of a new coronavirus, Reuters reported. 

Tickets for participation in the air show were returned to such major manufacturers as Lockheed Martin and Raytheon.

The number of those who refused to participate in the air show, which will be held from February 11 to 16, is less than 8%.
