Calcutta, March 6 :    Calcutta, March 6:  Indian Iron and Steel Company (IISCO) has decided to sell two aircraft acquired by the original promoter, Sir Biren Mukherjee, in 1960. The steel ministry has asked the Steel Authority of India (SAIL) to dispose all items that are of no use to plants but are retained by them for reasons of sentiment. Apart from two short-haul Beach Craft models, IISCO has offered to sell its 54 kms Chasnala-Burnpur ropeway on an 'as is where is and no-complaint' basis. IISCO is not the only SAIL outfit getting rid of unwanted assets. Durgapur Steel Plant (DSP) recently sold an open hearth furnace which had been replaced with a basic oxygen furnace in a revamp carried out in the mid 1990s. The two aircraft, with registration number VT-DMR Queen Air 54 and VT-DMQ Twin Bonanza D 50C, had recorded total flying hours of 7359.45 and 6182.55. These planes were extensively used for making sorties to mines and Sir Biren's base in Calcutta. After nationalisation in the early 80s, these planes were used primarily by political leaders, top SAIL and IISCO executives to fly to Calcutta airport for their onward journey to Delhi. Sources said the planes, almost grounded during the past two years because of high fuel and maintenance costs, had to wait for a directive from the Centre to be sold off The 54-km ropeway, which links coal and ore belts across Bihar and Bengal, has 10 stations spread over six sections. Moving buckets overhead carried coal, iron ore, dolomite and sand during the heydays of the IISCO plant in Burnpur. But now they will be valued for items like steel structures, buckets, CGI sheets, mechanical items like gear boxes, rollers and sheaves, diesel generating sets, copper and aluminium cables, control panels and 44m diameter track rope.
