As Mr Mohan has rightly pointed out if one is concerned so much he can depute his people or visit himself the area to boost the moral of relief agencies as well as local peopke. Such times going for aerial survey seems to be a formality.
Knowledge is power.

Even this challenging situation would ease
If CM from state or PM from center wants to have feel of loss they should go by road and see the affected areas and meet the people there and share their difficulties. Advise the concerned authorities to do the required help and see that people will not suffer long because of these natural calamities. If they can't go personally, they can depute their team and ask them to do the needy.
When there was a problem of Hudhud in Visakhapatnam of Andhra Pradesh, the role played by the CM of Andhra Pradesh is commendable. He personally camped in the affected area and gave instructions to the officers and he managed the normal life in the city in the shortest possible time. So far in the history of our Country no CM has acted like this. All appreciations to him. Today if you have a look at that city nobody will believe that there was a big damage to the city. Actually this is what needed than aerial surveys.
