Indian Air Forces' helicopter have joined the rescue operations in flood-hit Tuticorin, Tirunelveli, Tenkasi, and Kanyakumari districts, which were pounded by 'historic' rainfall over the last two days. The helicopters, known all over the world as the only five-chopper military display team, are being flown by the same pilots who fly the various formations. Only this time they are flying aid to the inundated areas. Nearly 40 lakh people in the Tirunelveli and Tuticorin districts have been affected by the record rains while Srivaikuntam and villages near Tiruchendur suffered great damages due to flooding.
