LTE International Airways S.A. (Lte Volar Airlines) was a charter airline based in Palma de Mallorca, Spain. It operated passenger charter services throughout Europe. Its main base was Son Sant Joan Airport, Palma de Mallorca with hubs at Reina Sofía Airport, Tenerife, Gran Canaria International Airport, Lanzarote Airport, Fuerteventura Airport and Barcelona International Airport. The airline was established on 29 April 1987, the founding shareholders being Spanish businessmen and the privately owned airline LTU from Germany. It started operations on 1 November 1987. From 1993 until May 2001, LTU was the sole owner having bought out the other original shareholders. On 24 May 2001, LTU sold the airline to a group of Spanish and Italian businessmen, including the Volare Group. As a result LTE was rebranded Volar Airlines. In 2005 the airline was renamed back to LTE International Airways. The airline was wholly owned by Gasarer. From July 2008, Lte operated flights between Norwich (UK) and Barcelona, Alicante and Palma de Mallorca, and from Winter 08/09 it hoped to fly from Norwich to Tenerife, Las Palmas and Málaga. On 16 October 2008, Lte abruptly announced that it was suspending all flights -both regular and charter- due to the financial situation of the company, which made it difficult to meet the next few days' operational expenses. Only the three aircraft operating for other airlines will be kept pending further decisions. It has subsequently announced a resumption of charter operations from 27 October 2008. On 27 October 2008, Lte announced on their web site they had resumed their charter activities and expected to re-open the on-line bookings, with no other details. It had continued limited ACMI operations on behalf of other carriers until 15 November 2008 when it finally suspended all operations.

The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was built by Boeing Commercial Airplanes from 1981 to 2004. It is the manufacturer's largest single-aisle passenger aircraft. The twinjet has a two-crewmember glass cockpit, turbofan engines, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design. Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 289 passengers for a maximum of 3,150 to 4,100 nautical miles (5,830 to 7,600 km), depending on variant. The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft. The 757 was produced in two fuselage lengths. The original 757-200 entered service in 1983; the 757-200PF, a package freighter (PF) variant, and the 757-200M, a passenger-freighter combi model, debuted in the late 1980s. The stretched 757-300, the longest narrow-body twinjet ever produced, began service in 1999. Passenger 757-200s have been modified to special freighter (SF) specification for cargo use, while military derivatives include the C-32 transport, VIP carriers, and other multi-purpose aircraft. Private and government operators have also customized the 757 for research and transport roles. All 757s are powered by Rolls-Royce RB211 or Pratt & Whitney PW2000 series turbofans. Eastern Air Lines and British Airways placed the 757 in commercial service in 1983. The narrow-body twinjet succeeded earlier single-aisle airliners, and became commonly used for short and mid-range domestic routes, shuttle services, and transcontinental U.S. flights. After regulators granted approval for extended overseas flights in 1986, airlines also began using the aircraft for intercontinental routes. Major customers for the 757 included U.S. mainline carriers, European charter airlines, and cargo companies. The airliner has recorded eight hull-loss accidents, including seven fatal crashes, as of June 2012. Production of the 757 ended on October 28, 2004, after 1,050 had been built for 54 customers. The 757-200 was by far the most popular model, with 913 built. Diminished sales amid an airline industry trend toward smaller jetliners led Boeing to end production without a direct replacement, in favor of the 737 family. The last 757 was delivered to Shanghai Airlines on November 28, 2005. In 2011, 898 of the narrow-body twinjets were in airline service, and Delta Air Lines was the largest operator, with 185 aircraft.
