Since 2002, 40 missions have been organised over the UK. There were 24 quota missions carried out by: Russia – 20; Ukraine – three; and Sweden – one. There were 16 training flights from: Benelux (jointly with Estonia); Estonia (in conjunction with the Benelux); Georgia – three (a commune with Sweden); Sweden – three (a commune with Georgia); United States – three; Latvia; Lithuania; Romania; Slovenia; Yugoslavia.  Also since 2002, the United Kingdom has carried out a total of 51 open-air missions – 38 quota missions in the following countries: Ukraine (five); Georgia (seven) and Russia (26); 13 missions were training missions in the following nations: Bulgaria; Yugoslavia; Estonia; Slovenia (three); Sweden (three); United States; Latvia, Lithuania and Benelux. Flights cost approximately $50,000 per mission and approximately $25,000 for training missions with approximately $175,000 per year.  Let us not kid ourselves: Russia is solely responsible for these developments and the continued erosion of the arms control architecture. We maintain effective arms control that promotes the security of the United States, allies and partners, which is verifiable and enforceable, and includes partners who carry out their obligations responsibly. But we cannot remain in arms control agreements that are violated by the other side and are actively used not to support, but to undermine international peace and security. As I have already said, we may be ready to reconsider this decision if Russia demonstrates a return to full compliance with this treaty of trust, but without such a change of course from the Kremlin, our path will lead to withdrawal in six months.
The “open skies” treaty is indefinite and open to the accession of other states. The republics of the former Soviet Union (U.S.S.R.), which are not yet contracting parties, can join at any time. Applications from other interested countries are subject to a consensus decision by the Open Skis Advisory Board (OSCC).  Since it came into force in 2002, eight countries have joined the treaty: Bosnia and Herzegovina, Croatia, Estonia, Finland, Latvia, Lithuania, Slovenia and Sweden. Austria, Cyprus, Ireland, Switzerland, Serbia, Montenegro, Albania, Northern Macedonia, Moldova, Armenia and Uzbekistan are particularly absent. The Republic of Cyprus applied to join the treaty in 2002; But since then, Turkey has blocked its accession. [Citation required] Since then, the United States has entered into open partnerships with more than 120 countries or organizations around the world. In the face of increased competition, airlines have been forced to find efficiencies, develop innovations with new routes and try new service models to deliver higher value to customers. The cumulative impact on the international travel industry has been enormous. Data from the U.S. Travel Association show that prices on routes covered by open skies have fallen by 30%, saving travelers billions of dollars a year.
While many open-ski agreements have already been signed, which help create multiple options for the modern traveller, there are still great advantages to be realized through future agreements. The “open skies” contract came into effect in January 2002 and covers areas from Vancouver to Vladivostock. The treaty provides for a system of unarmed air observation flights throughout the territory of its 34 signatories. It aims to strengthen mutual understanding and trust by giving all participants, regardless of size, the opportunity to obtain information about military or other activities that affect them. Open skies is the most important international effort to date to promote the openness and transparency of the armed forces and their activities. The open skies policy began in the early 1990s with the United States.
