Mumbai, May 3 : Mumbaikars looked up in the sky with amazement as the Tri-Services accorded a grand aerial salute with showers of flowers and petals acknowledging the work of the frontline warriors in the war against the virus here on Sunday morning. Helicopters and fighter planes flew over the empty but picturesque Marine Drive and other parts of Mumbai as the Indian Army, Indian Navy and Indian Air Force came out to pay tributes to the doctors, nurses, sanitation workers, police and others involved in the fight against COVID-19. Helicopters flew around certain key hospitals treating Covid-19 patients like the INS ASHVINI, Sir J. J. Hospital, KEM hospital and the Kasturba Hospital. The Sukhoi-30 aircraft flew in a march-past from the Raj Bhavan to Marine Driver while MI-17 and Chetak choppers showered flowers on the hospitals situated in congested localities of South Mumbai, mesmerising the citizens cooped up in their homes. /IANS
