When we started out with the modalities, we were absolutely clear that 1,90,000, is a conservative number. If you have to bring all of them, it will become a major exercise. First, we had to prioritise among the people who wanted to come back. No matter what precautions you take, no matter how careful you are, international travel at the time of a pandemic is fraught with risks. Various measures such as disinfecting the aircraft, wearing masks and screening at the point of evacuation pre-boarding the flight were in place. Asymptomatic passengers are a risk factor. However, we want to minimise the risk of spreading the infection. When the passengers arrive at the respective airports, there have to be proper arrangements, as per protocol. The most important thing when you deal with large numbers is that the receiving state governments must have quarantine arrangements in place.
