San Francisco, July 10 : Facebook discontinued last year a small helicopter drone project that could temporarily replace cellular services in emergency situations, The Verge reported.

The project was discontinued a few months after being shown off at the F8 developer conference in May of 2017, said the report on Monday.

"Tether-tenna was a proof of concept project we were evaluating when we discussed it at F8 in early 2017," a spokesperson for Facebook was quoted as saying.

The idea was to send a helicopter equipped with telecommunications equipment hundreds of metres up in the air to be able to tether to fiber and power lines in places where wireless capacity was compromised due to disaster or other factors.

"It wasn't something we pursued further as we chose to focus our efforts on continued development and advancement of our Terragraph, millimeter-wave, and HAPS (high altitude platform station) programmes," the Facebook spokesperson added.

The Tether-tenna is, however, not the only aerial Internet project that Facebook has abandoned in recent times.

In June this year, Facebook announced it decided to abandon its plan to develop high-flying solar-powered drones called Aquila that was aimed to deliver Internet to nearly four billion people in remote parts of the world.

A high altitude platform station (HAPS) system, Aquila's mission, according to Facebook CEO Mark Zuckerberg, was to connect the world and help people who do not have online access all the opportunities of the Internet.

Facebook began Aquila project in 2014. In 2017, the solar-powered drone successfully completed the second full-scale test flight.

Tether-tenna was a much smaller scale idea compared to Aquila.

Visakhapatnam (PTI): India fought back gallantly through Prasidh Krishna and Kuldeep Yadav after Quinton de Kock struck his 23rd hundred, keeping South Africa to a manageable 270 in the third and series-deciding final ODI, here Saturday.

India won the toss after judging the spin of the coin incorrectly 20 times in a row. They had little hesitation in inserting the Proteas into bat, a clear indication of dew factor dominating the thought.

After Arshdeep Singh sent back Ryan Rickelton early, De Kock (106, 89b, 8x4, 6x4) struck his seventh century against India and put on 113 runs off 124 balls with skipper Temba Bavuma (48, 67b) as the visitors moved to a healthy position.

De Kock was severe on Prasidh (4/66), who erred on length continuously in his first spell (2-0-27-0). The left-hander biffed the pacer for 6, 6, 4 in his second over to milk 18 runs.

The 32-year-old quickly pounced on anything that was short, and pacers Prasidh and Harshit offered him plenty of feed on his pet areas.

Bavuma was more sedate, and made runs through those typical dabs and jabs, occasionally unfurling a drive of elan.

De Kock moved to fifty in 42 balls, and never let the tempo down reaching his hundred in 79 balls.

India found temporary relief when Ravindra Jadeja induced a false slash from Bavuma to get caught by Virat Kohli at point.

The tourists got another move on through a 54-run partnership between De Kock and Matthew Breetzkle for the third wicket, and at 168 for two in 28 overs they were in a good position to press on.

But Breetzke's punishment of part-time spinner Tilak Varma forced a rethink in the Indian camp, as skipper KL Rahul brought back Prasidh for a second spell.

What a masterstroke it turned out to be! The Karnataka man broke the back of South Africa’s top and middle order in an exceptional second spell (4-0-11-3).

Breetzke was the first man to go, trapped plumb in front with a straight one and four balls later Aiden Markram uppishly chipped a fuller delivery to Kohli at short covers.

Prasidh soon castled De Kock, whose ugly cross-batted swipe failed to connect a full length delivery from the pacer.

All of a sudden, SA found themselves at a shaky 199 for five, losing three wickets in the space of three overs.

Once Prasidh was done away with the top and middle-order, left-arm wrist spinner Kuldeep (4/41) took over and mopped up the tail as SA fell short of even a par total on this track.
