L. Ponnudurai
Four years ago, L. Ponnudurai was cleaning tables at a restaurant in Rajapalayam bus depot. In a month from now, he will begin work in a reputed cement company, as a chemical engineer.
The story of this gritty Dalit boy from Gopalapuram village near Rajapalayam in southern Tamil Nadu is an inspiring one. When he was barely five years old, his mother had committed suicide. Soon after this, his father remarried and sent him away to his grandmother’s place.
A relative noted his keenness to learn and put him in a government Adi Dravidar hostel. “My relatives were mill labourers and earned very little. To avoid burdening them, I used to stay in the hostel even during holidays,” said Ponnudurai.
He scored 96 per cent in Class X, and friends suggested a vocational course at a polytechnic institute. But, Ponnudurai said, he was keen on studying further.
Scholarships helped him finish Class XII with 93 per cent. He, however, faced a roadblock when he wanted to pursue his dream of going to college, as he did not have money to buy a form and apply for engineering counselling.
One day, his former physics teacher spotted him working at Vasantha Bhavan in Rajapalayam. “The next day, all my teachers landed up there. They had pooled in money to send me to Chennai and apply for engineering,” said Ponnudurai.
But this was not the end of Ponnudurai’s struggle. He tried to apply for an education loan all on his own, but bank officials wanted his father to be present. “He came only after my school teachers pleaded with him and promised to pay for his travel,” he added.
Ponnudurai came to Chennai with Rs. 2,000 and two pairs of clothes, but these were not his concerns. “Having studied in Tamil, learning in English was very difficult,” he said. Taunts over his complexion or his trousers almost broke his will. “I ran away thrice from campus, vowing never to return, but friends persuaded me to go back. In the hostel, I kept to myself,” he said.
But now, life is looking up. He recently cleared a recruitment interview with Ramco Cements and has got a decent offer. “I cannot ask for more.They let me answer questions in Tamil. I did not want to work in an IT company. I studied chemical engineering and I really like the subject,” he said, smiling. He has other plans too. “In villages, even bright students are unaware of opportunities, admission procedures, and scholarships. I want to convince students there to finish college,” he said.

Indonesian rescue workers help remove a section of a Lion Air Boeing 737 four days after it crashed into the sea near Bali
For all the headline-grabbing stories about security breaches, intoxicated pilots and faulty equipment, sometimes a commercial plane’s worst enemy is Mother Nature.
That appears to be the case for a new Boeing 737, operated by Indonesian budget carrier Lion Air, that crashed into the shallow waters off the coast of Bali on 13 April, just short of the runway at Ngurah Rai Airport. At the helm was an experienced pilot who managed to save all 108 passengers and crew, but told Reuters it felt like his aircraft was “dragged” down by wind as he fought to regain control. The crash – and the pilot’s alarming comments – are renewing fears about the chilling phenomenon known as windshear.
A windshear or “microburst” is a sudden change in wind speed and direction that can cause planes to rapidly lose altitude. They are often caused by storms creating strong downdrafts of wind.
Airplanes rely on wind speed and direction to control takeoff and landing, typically doing so in the direction of the wind. But sudden shifts in wind speed and direction can cause planes to lose control, especially during takeoff and landing, when they are low to the ground and have reduced engine power and little room to manoeuvre.
How likely is it that Lion Air’s crash was caused by a windshear? Officials from a bevy of agencies – including Indonesian state officials, the US National Transportation Safety Board, the Federal Aviation Administration (FAA), theMeteorological and Geophysics Agency and Boeing – are investigating the incident and expect to release their findings within a month. But initial tests show that the pilot was experienced, was not under the influence of drugs or alcohol, and the plane, a brand new Boeing 737, had no technical issues, all of which rules out pilot or plane error.
What’s more, weather reports indicate a strong storm and driving rains were developing as the plane attempted to land, which lends support to the idea of windshear as the culprit.
But the surprising – and unnerving – point is that aviation officials consider windshear to be a problem that was solved long ago. Between 1964 and 1985 windshear was responsible for some 26 civil aircraft crashes in the US, leaving about 500 fatalities and about 200 injuries, according to NASA. The most famous incident involved a Delta Airlines Lockheed Tristar, which crashed in 1985, killing 134 passengers and crew near the Dallas-Fort Worth airport.
Since then, windshear-related incidents have dropped considerably, thanks to FAA- and NASA-developed technology that warns pilots of oncoming storms. The Predictive Windshear System, available below 700m, warns pilots some 10 to 40 seconds ahead of windshear to go around the bursts.
But for now, a lot of unknowns remain, including whether the Lion Air crash was caused by windshear, whether the windshear warning system was functioning on the aircraft and perhaps the biggest question for the airline industry – whether windshear may again become a serious concern.
