New Delhi, Oct 15: From being the people's President to spearheading the development of the most significant Indian missiles, late President Dr APJ Abdul Kalam has contributed to the development of the country in different spheres.

As an aerospace scientist, Kalam worked with India's two major space research organisations - Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO).

While, his work in the development and operationalisation of Indigenous guided missiles - AGNI and PRITHVI - earned him the title of the 'Missile Man of India,' there are many more ways in which Kalam has helped India in the division of science and technology.

On the 89th birth anniversary of Dr APJ Abdul Kalam, here are 5 of his scientific contributions to the country: -

1. Directed the project to develop India's first Satellite Launch Vehicle (SLV)

Back in 1980s, when India had hardly dreamt of having its indigenous Satellite Launch Vehicle (SLV), Dr Kalam's over 10-year-long hard work as the project director for the development of the indigenous Satellite Launch Vehicle at ISRO led to the ground-breaking scientific development.

It was in July 1980, that India's SLV-III successfully deployed the Rohini satellite in the near-Earth orbit leading to the country becoming a member of the exclusive Space Club.

2. Directed projects for the development of ballistic missiles

Kalam also headed the projects Devil and Valiant which had the aim of developing ballistic missiles using the technology behind the successful SLV program. Under mission Kalam with other projects, members developed many missiles including AGNI which is an intermediate-range ballistic missile and PRITHVI which is a surface-to-surface missile.

3. Headed multiple nuclear tests at Pokhran

Serving as the Chief Scientific Adviser to the then Prime Minister, Kalam played a major role in heading the Pokhran-II nuclear testing leading to him being known as the best nuclear scientist of the country at that time. The nuclear testing under the supervision of Kalam during the period of July 1992 to December 1999 made India a nuclear-armed state.

4. He worked in making healthcare accessible to all

Working jointly with cardiologist Soma Raju, the late President developed a cost-effective coronary stent 'Kalam-Raju Stent' which helped in making healthcare accessible to all.

5. Developed the rugged 'Kalam-Raju tablet'

The duo of Kalam and Soma Raju later in 2012 designed a rugged tablet computer for better health care administration in the rural pockets of the country. They termed it the 'Kalam-Raju tablet.'

For his work in the stream of science and politics, the 11th President was also awarded India's highest civilian honour or the Bharat Ratna.

Kalam breathed his last on July 27, 2015, while delivering a lecture at the Indian Institute of Management Shillong when he collapsed and died from a cardiac arrest.

Five years after his demise, his contributions are still remembered as some of the best scientific and technological developments in the country.

The deletion of over 58 lakh names from West Bengal’s draft electoral rolls following a Special Intensive Revision (SIR) has sparked widespread concern and is likely to deepen political tensions in the poll-bound state.

According to the Election Commission, the revision exercise has identified 24 lakh voters as deceased, 19 lakh as relocated, 12 lakh as missing, and 1.3 lakh as duplicate entries. The draft list, published after the completion of the first phase of SIR, aims to remove errors and duplication from the electoral rolls.

However, the scale of deletions has raised fears that a large number of eligible voters may have been wrongly excluded. The Election Commission has said that individuals whose names are missing can file objections and seek corrections. The final voter list is scheduled to be published in February next year, after which the Assembly election announcement is expected. Notably, the last Special Intensive Revision in Bengal was conducted in 2002.

The development has intensified the political row over the SIR process. Chief Minister Mamata Banerjee and her Trinamool Congress have strongly opposed the exercise, accusing the Centre and the Election Commission of attempting to disenfranchise lakhs of voters ahead of the elections.

Addressing a rally in Krishnanagar earlier this month, Banerjee urged people to protest if their names were removed from the voter list, alleging intimidation during elections and warning of serious consequences if voting rights were taken away.

The BJP, meanwhile, has defended the revision and accused the Trinamool Congress of politicising the issue to protect what it claims is an illegal voter base. Leader of the Opposition Suvendu Adhikari alleged that the ruling party fears losing power due to the removal of deceased, fake, and illegal voters.

The controversy comes amid earlier allegations by the Trinamool Congress that excessive work pressure during the SIR led to the deaths by suicide of some Booth Level Officers (BLOs), for which the party blamed the Election Commission. With the draft list now out, another round of political confrontation appears imminent.

As objections begin to be filed, the focus will be on whether the correction mechanism is accessible, transparent, and timely—critical factors in ensuring that no eligible voter is denied their democratic right ahead of a crucial election.

New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.

Domestic carrier IndiGo has cancelled over 180 flights from three major airports — Mumbai, Delhi and Bengaluru — on Thursday, December 4, as the airline struggles to secure the required crew to operate its flights in the wake of new flight-duty and rest-period norms for pilots.

While the number of cancellations at Mumbai airport stands at 86 (41 arrivals and 45 departures) for the day, at Bengaluru, 73 flights have been cancelled, including 41 arrivals, according to a PTI report that quoted sources.

"IndiGo cancelled over 180 flights on Thursday at three airports-Mumbai, Delhi and Bengaluru," the source told the news agency.

Besides, it had cancelled as many as 33 flights at Delhi airport for Thursday, the source said, adding, "The number of cancellations is expected to be higher by the end of the day."

The Gurugram-based airline's On-Time Performance (OTP) nosedived to 19.7 per cent at six key airports — Delhi, Mumbai, Chennai, Kolkata, Bengaluru and Hyderabad — on December 3, as it struggled to get the required crew to operate its services, down from almost half of December 2, when it was 35 per cent.

"IndiGo has been facing acute crew shortage since the implementation of the second phase of the FDTL (Flight Duty Time Limitations) norms, leading to cancellations and huge delays in its operations across the airports," a source had told PTI on Wednesday.

Chaos continued at several major airports for the third day on Thursday because of the cancellations.

A spokesperson for the Kempegowda International Airport (KIA) in Bengaluru said that 73 IndiGo flights had been cancelled on Thursday.

At least 150 flights were cancelled and dozens of others delayed on Wednesday, airport sources said, leaving thousands of travellers stranded, according to news agency Reuters.

The Directorate General of Civil Aviation (DGCA) has said it is investigating IndiGo flight disruptions and has asked the airline to submit the reasons for the current situation, as well as its plans to reduce flight cancellations and delays.

It may be mentioned here that the pilots' body, Federation of Indian Pilots (FIP), has alleged that IndiGo, despite getting a two-year preparatory window before the full implementation of new flight duty and rest period norms for cockpit crew, "inexplicably" adopted a "hiring freeze".

The FIP said it has urged the safety regulator, the DGCA, not to approve airlines' seasonal flight schedules unless they have adequate staff to operate their services "safely and reliably" in accordance with the New Flight Duty Time Limitations (FDTL) norms.

In a letter to the DGCA late on Wednesday, the FIP urged the DGCA to consider re-evaluating and reallocating slots to other airlines, which have the capacity to operate them without disruption during the peak holiday and fog season if IndiGo continues to "fail in delivering on its commitments to passengers due to its own avoidable staffing shortages."
