Question: Which airline merged with the company with who Prem Mathur worked for in 1953?

Hunting-Clan Air Transport was a wholly private, British independent airline that was founded in the immediate post-World War II period.  It began trading on January 1, 1946 as Hunting Air Travel Ltd.  It was a subsidiary of the Hunting Group of companies, which had come from the shipping industry and could trace its history back to the 19th century.  The newly formed airline's first operating base was at Bovingdon Airport in Southeast England.  Its main activities were contract, scheduled and non-scheduled domestic and international air services that were initially operated with Douglas Dakota and Vickers Viking piston airliners from the company's Bovingdon base.  A change of name to Hunting Air Transport occurred in 1951.  By that time, the airline had emerged as one of the healthiest and most securely financed independent airlines in Britain.  In October 1953, the firm's name changed to Hunting-Clan Air Transport, as a result of an agreement between the Hunting Group and the Clan Line group of companies to invest £500,000 each in a new company named Hunting-Clan Air Holdings Ltd, the holding company for the combined group's air transport interests.  Apart from Hunting-Clan Air Transport itself, this included Field Aircraft Services Ltd, the Hunting group's aircraft maintenance arm.  In 1960, Hunting-Clan Air Transport merged with the Airwork group to form British United Airways (BUA). <SEP> British Aviation Services Limited (Britavia) was an early post-World War II airline holding company and air transport operator that could trace its roots back to 1946.  Its main activities included trooping, inclusive tour (IT) and worldwide passenger and freight charter services. British Aviation Services' first investment in a British independent airline occurred in 1946, when it acquired a minority interest in Silver City Airways.  Silver City Airways operated the world's first cross-Channel air ferry service on 13 July 1948.  It subsequently became British Aviation Services' biggest operating division.  In 1953, British Aviation Services took over the independent airline Air Kruise.  The same year, BAS Group also took control of Aquila Airways, the last commercial flying boat operator in the United Kingdom.  The completion of these acquisitions by mid-1954 resulted in a reorganisation of the British Aviation Services group, with British Aviation Services Ltd (BAS Group) becoming the group's holding company and Britavia one of its operating subsidiaries.  By the late 1950s, BAS Group became Britain's largest independent airline operator.  Its numerous operating divisions included Britavia's Hermes Division at Blackbushe Airport and Aquila Airways's Flying Boat Division at Hamble near Southampton.  The former concentrated on trooping services and inclusive tours while the latter provided scheduled services to Portugal, the Canary Islands and Italy.  In 1962, BAS Group merged with British United Airways (BUA), which by that time had replaced BAS as the UK's largest independent airline operator. <SEP> Deccan Airways Limited was a commercial airline based in Hyderabad.  Founded in 1945, it was one of the nine airlines existing in India during independence.  The airline, a joint venture of Nizam Government of erstwhile Hyderabad State and Tata Airlines was launched with a fleet of three aircraft.  The airline operated on Madras-Hyderabad-Nagpur- Bhopal-Gwalior-Delhi, Hyderabad-Bombay and Hyderabad-Bangalore sectors.  By the time it was merged with Indian Airlines in 1953, it had a fleet of thirteen Douglas DC-3 'Dakota' aircraft. <SEP> Prem Mathur is the first Indian woman commercial pilot and started flying for Deccan Airways.  She obtained her commercial pilot's licence in 1947.  In 1949 she won the National Air Race.
