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

<P0-S0> Hunting-Clan Air Transport was a wholly private, British independent airline that was founded in the immediate post-World War II period. <P0-S1>  It began trading on January 1, 1946 as Hunting Air Travel Ltd. <P0-S2>  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. <P0-S3>  The newly formed airline's first operating base was at Bovingdon Airport in Southeast England. <P0-S4>  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. <P0-S5>  A change of name to Hunting Air Transport occurred in 1951. <P0-S6>  By that time, the airline had emerged as one of the healthiest and most securely financed independent airlines in Britain. <P0-S7>  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. <P0-S8>  Apart from Hunting-Clan Air Transport itself, this included Field Aircraft Services Ltd, the Hunting group's aircraft maintenance arm. <P0-S9>  In 1960, Hunting-Clan Air Transport merged with the Airwork group to form British United Airways (BUA). <SEP> <P1-S0> Prem Mathur is the first Indian woman commercial pilot and started flying for Deccan Airways. <P1-S1>  She obtained her commercial pilot's licence in 1947. <P1-S2>  In 1949 she won the National Air Race. <SEP> <P2-S0> 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. <P2-S1>  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. <P2-S2>  Silver City Airways operated the world's first cross-Channel air ferry service on 13 July 1948. <P2-S3>  It subsequently became British Aviation Services' biggest operating division. <P2-S4>  In 1953, British Aviation Services took over the independent airline Air Kruise. <P2-S5>  The same year, BAS Group also took control of Aquila Airways, the last commercial flying boat operator in the United Kingdom. <P2-S6>  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. <P2-S7>  By the late 1950s, BAS Group became Britain's largest independent airline operator. <P2-S8>  Its numerous operating divisions included Britavia's Hermes Division at Blackbushe Airport and Aquila Airways's Flying Boat Division at Hamble near Southampton. <P2-S9>  The former concentrated on trooping services and inclusive tours while the latter provided scheduled services to Portugal, the Canary Islands and Italy. <P2-S10>  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> <P3-S0> Deccan Airways Limited was a commercial airline based in Hyderabad. <P3-S1>  Founded in 1945, it was one of the nine airlines existing in India during independence. <P3-S2>  The airline, a joint venture of Nizam Government of erstwhile Hyderabad State and Tata Airlines was launched with a fleet of three aircraft. <P3-S3>  By the time it was merged with Indian Airlines in 1953, it had a fleet of thirteen Douglas DC-3 'Dakota' aircraft. <P3-S4>  The airline operated on Madras-Hyderabad-Nagpur- Bhopal-Gwalior-Delhi, Hyderabad-Bombay and Hyderabad-Bangalore sectors.
