to numerous destinations including New York City, Chicago, Toronto aboard its McDonnell Douglas DC-10 aircraft. These long haul services inevitably had a major impact on air traffic at Zagreb during that period. On 31 August 1991, during the Croatian War of Independence, the airport became the scene of fighting between Croatian armed forces and the Yugoslav People's Army (JNA) when a Boeing 707 chartered by Anton Kikaš carrying weapons for the Croatians was forced to land there by Yugoslav MiGs. Croatian forces attacked the control tower and blocked roads in and out of the airport, but the JNA successfully seized the 707 and flew it out of the airport. The airport later became a UN hub for getting food and medical supplies to war-ridden Croatia and Bosnia. The British 24th Field Ambulance were stationed in a former JNA camp at the airport. Following an increase in passenger numbers and the necessity to upgrade its infrastructure, the airport installed a CAT-IIIb instrument landing system (ILS) in 2004. In 2008, a new VIP terminal was added and the terminal was extended to include extra amenities, restaurants and bars. The terminal was expanded to . By 2010, the old terminal was nearing its maximum annual capacity. That year the passenger terminal received a major facelift in the course of which a viewing platform with a bar was added. On 12 April 2012, the ZAIC consortium received a 30-year concession for the airport from the Government of Croatia. The consortium consists of Groupe ADP (21%), Bouygues Bâtiment International (21%), Marguerite Fund (21%), International Finance Corporation (17%), TAV Airports (15%) and Viadukt (5%). The concession includes financing, designing and constructing a new passenger terminal. The construction of a brand new terminal facility designed by Neidhardt architects of Zagreb and carried out by Bouygues Bâtiment International in partnership with Viadukt began on 18 December 2013 with the aim to replace the old terminal. It now has an initial annual capacity of 5.5 million passengers in the first phase and was officially completed in October 2016. The official inauguration of the terminal was on 28 March 2017. ZAIC now operates the entire airport, including the runways, passenger terminal, cargo terminal, car parks and future property developments, under a 30-year concession. This contract involves a total investment of around €324 million: €236 million for the design and construction of the new terminal and €88 million for operation of
