Emirates Airline president Sir Tim Clark  believes the US aviation industry would suffer if the system of Open Skies agreements falls apart.
 Clark  says international demand for air travel and aircraft have skyrocketed since the first of more than 120 Open Skies agreements were signed in 1992.
 Emirates Airline president Sir Tim Clark  believes the US aviation industry could become a victim of the trade dispute centered around the Open Skies agreements that govern air travel between the US and the United Arab Emirates where  his  airline is based.
 This  Clark  believes  threatens to weaken the network of Open Skies agreements that have served the aviation industry so well over the past couple of decades.
REUTERS/Satish Kumar "When the US went Open Skies I thought it was the best thing because if the US had done it then everybody would follow suit "  Clark  told us.
"I know that as a result of what they did  the number of planes Boeing sold went nuclear "  Clark  declared. "Because the number of aircraft sold was a direct function of the Open Skies versus closed skies relationship."
