Bengaluru, Jan 26 (IANS): An Indian Air Force (IAF) helicopter kicked up a huge cloud of dust when it flew low over the Manekshaw parade ground in the city centre where the 71st Republic Day celebrations were held on Sunday.

"The IAF chopper flew at a low level (50-75 metres) over the ground while showering flowers as a welcome gesture, kicking up massive dust all around and forcing the gathering to cover their faces," a state official told IANS.

As part of the R-Day event every year, a military chopper flies over the ground from an altitude of 500 metres showing flowers to greet the crowds participating in the event.

As the chopper flew over the VIP area, state Governor Vajubhai Vala, Chief Minister B.S. Yediyurappa and other dignitaries, including invitees were engulfed by the dust as it hit them in their faces.

"The IAF pilots were forced to fly the chopper at a low level as a flock of birds, including eagles were circulating over the ground at the same time and encountering them would have resulted in a mishap," a defence official told IANS.

With the soil on the parade ground dry and loose after rehearsals were conducted on Friday, a blast of wind from the low-flying chopper kicked up the fine dust particles upto 10 feet high.

Hundreds of spectators, including VIPs were seen taking cover to escape the 'dust storm' the aircraft caused.
