Mumbai, Nov. 29 :    Mumbai, Nov. 29:  He looked calm and composed in his neatly-pressed suit and blow-dried hair, hardly a man who claimed to have gone through hell. Now reinstated Air-India managing director Michael Mascarenhas was ready to embark on a new mission on his last day in office. 'I went through a state of shock and trauma. I did not know what to tell my 90-year-old mother, who kept asking for the details,' he said, hours after the civil aviation ministry withdrew his suspension. Mascarenhas returned today to the 24th floor boardroom in Air India Building on Nariman Point overlooking the Arabian Sea. But his return was largely symbolic as he is due to retire tomorrow. After the CBI cleared him of corruption charges for lack of evidence, civil aviation minister Shahnawaz Hussain ordered his reinstatement almost immediately, though for a brief two days, largely to stay clear of legal wrangles. The ministerial gesture at least helped Mascarenhas save his face to some degree, a colleague said. But the rage and humiliation of the 'unfair, unjust and now illegal' suspension spilled out as the suave official spoke to the media for the last time as head of the nation's carrier. 'I wish action would be taken against those who have maligned me by framing me up,' Mascarenhas, 58, said, refusing to point finger at anybody. He said he was going to withdraw the civil suit he had filed with the Bombay High Court, challenging his suspension. He had no plans to pursue those who had pursued him. He felt that in post-Tehelka India, anybody with a Rs 5 stamp paper could file an affidavit and frame somebody. 'You can malign anybody now and the onus is on the accused person to prove his innocence,' Mascarenhas said. What's worse, people now tend to believe what they are told, he added. The Air India chief was suspended on May 23 after the CBI accused him of granting undue favours to an UK-based sales agent. This was grossly irregular and tantamount to corruption in high places, the bureau had said. The CBI exonerated the official yesterday, saying 'no irregularity of any kind can be associated' with the Air India chief. Mascarenhas said he still had Air India's interest in his heart. One of his unrealised dreams was to see it grow from a 31-aircraft fleet to one with 50 planes. The Air India boss said his airline was starved of funds, while Indian Airlines was bankrolled by the Union government. And this was all he would say on the proposed disinvestments of the state-run airline. Though suspension had cost him six months of service, Mascarenhas said he was not going to seek extension. 'Why should I? It's so demeaning,' he said. 'Moreover, I have brought down the retirement age to 58 years at Air India and I have no intention of violating that.'
