report by Swiss technology company RUAG the Air Force had lost nearly half of its (combat) aircraft (since early 2014). RUAG believed that 222 of the Air Force's 400 aircraft had been lost. Since 12 July 2014 the Ukrainian Air Force has been put on full combat alert. Around this date the Air Forces started restoring its former military airfields in Voznesensk, Buyalyk and Chervonohlynske (both in Odessa Oblast). Ukraine inherited a large inventory of aircraft from the Soviet Union, these were mostly decommissioned and stored as the nation had little use or funding to keep a large fleet active. In 2014, the air force announced that it will be bringing back 68 aircraft that have been in reserve since the collapse of the Soviet Union, including the Tupolev Tu-141 reconnaissance drone. In April 2014 two MiG-29 aircraft were restored. In August a decommissioned An-26 transport aircraft was also restored to active service by a volunteer group. On 5 January 2015 the air force received another 4 newly restored airplanes, two MiG-29s and two Su-27s, as well as two Mi-8 and Mi-2 helicopters. As a result of the war in Donbas the government of Ukraine has realized the importance of drone surveillance in locating enemy troops and recommissioned 68 Soviet era Tu-141 drones to be repaired. Analysts point out that despite being designed in 1979 the Tu-141 has a powerful camera, it likely uses similar airborne radar and infrared sensor as the Soviet-era Su-24 which would make it prone to jamming by Russian forces as they use the same equipment. A crowd funding project for a "people's drone" was also conducted. The goal was to collect funds to purchase an already functioning American or Israeli drone. However, Ukrainian designers and engineers were able to build their own model based on the commercially available DJI Phantom 2 drone. In October 2014, students from Ivano-Frankivsk designed their own drone to be used in the war in Donbas. The newly build drone has the ability to broadcast footage live, unlike the Tu-141 which relies on film that must be recovered. The drone was built from off the shelf components and funded by volunteers. The drone was also stated to have an operational ceiling of 7,000 meters, a range of 25 kilometers, and cost about US$4,000 to build. Ukroboronprom has received an order for ₴2.5 million ($166,000) to refit several Mil Mi-24 helicopter gunships
