Regional jet aircraft types northwest air
The HAL/NAL Regional Transport Aircraft ( RTA ) is a project of Hindustan Aeronautics Limited (HAL) and National Aerospace Laboratories (NAL). It is also known as the Indian Regional Jet (IRJ). This aircraft is claimed to be a turboprop or a jet with a capacity of 70-100 passengers. The basic version will have 80-90 seats (RTA-70). 
In 2007 Hindustan Aeronautics Limited (HAL) and the National Aerospace Laboratories (NAL) jointly designed and developed a 70-seater civil regional aircraft. NAL had held discussions with Pratt and Whitney (Canada) and General Electric (U.S.) for an engine. The NAL-designed RTA-70 is meant to ply short-haul routes and compete with planes of French-Italian aircraft maker Avions de Transport Régional (ATR), a leading exporter of turbo-prop aircraft to the Indian sub-continent. 
In 2008, the Indian government through the Ministries of Defence and Civil Aviation have approved the plan and have asked HAL to prepare a roadmap for the project. It will not be an indigenous venture as the government is planning to enter into a memorandum of understanding with major names in the industry like Embraer , Bombardier Aerospace  or United Aircraft Corporation . The aircraft was expected to fly in six to seven years.
The aviation authorities of Cuba have ordered the grounding of the entire Antonov An-158 fleet operated by Cubana de Aviación, the Caribbean island nation’s flag carrier and the world’s only commercial operator of the type, according to publicly-available official notices.
In their resolution, the Cuban regulators explain that the grounding is the consequence of a number of problems associated with the operation of the Ukrainian-designed jet, including a shortage and unreliable delivery of component parts for the aircraft which are, to a great extent, produced in Russia .
The Antonov An-158 is a 100-seat regional jet, a stretched version of the An-148, which was designed and built in the Ukraine using many Russian components, in a project originally financed by a group of Russian banks. It was also a Russian lease company which organised a deal for the aircraft with Cuba. Against the difficult backdrop, cooperation between Russia and Ukraine remains fractured.
The Mitsubishi Regional Jet ( Japanese : 三菱リージョナルジェット ), or MRJ for short, is a twin-engine regional jet aircraft seating 70–90 passengers manufactured by Mitsubishi Aircraft Corporation , a partnership between majority owner Mitsubishi Heavy Industries and minority owner Toyota Motor Corporation  with design assistance from Toyota affiliate Subaru Corporation , itself already an aerospace manufacturer. The MRJ will be the first airliner designed and produced in Japan since the NAMC YS-11 of the 1960s, which was produced at a loss.  
The first flight of the MRJ was in November 2015.  After several delays, deliveries are now scheduled to start by mid-2020. 
In 2003 the Japanese government started a five-year, ¥50 billion ($420 million) research program to study an indigenous regional jet for 30 to 90 passengers, led by Mitsubishi Heavy Industries (MHI).  In 2004 MHI was focused on a 2m high by 2.8m-wide, four-seat abreast cabin , seating 30 to 50 passengers, and was hoping to fly a prototype in 2007 and deliver the first aircraft in 2010.  In 2005 it switched to a larger 70-90 seat category. 
When Hollywood star John Travolta lands his historic Boeing 707 plane — registration 707JT — at Illawarra Regional Airport, it will be a significant coup for Bob De La Hunty.
Mr De La Hunty is the president and founder of the Historic Aircraft Restoration Society (HARS) and saved the Constellation from an American aviation graveyard in a labour of love that cost millions of dollars.
"We share a mutual respect for old airplanes and flying and at that stage we were keen to suggest to him that if he ever wanted to part with his Boeing 707 we would be very interested in it," Mr De La Hunty said.
