Were those aliens in Sandton? No, it was FutureLife of a different kind

JOHANNEBSURG - UFO sightings. Strange lights in the sky. Unexplained crash sites. Could it all just be coincidence ... or were there aliens in Sandton?

Well, as it turns out there is a more plausible explanation for some of the odd occurrences in and around Johannesburg's business district.

One of EWN's intrepid alien hunters (read "journalist") did some digging and in true sci-fi style found a folder with the words "Top Secret" stamped on it. She knew she'd found something important.

Okay, that didn't really happen. But we did speak to food producer FutureLife which says a UFO landing at the corner of Sandton Drive and William Nicol was in fact the big reveal for its new energy drink.

The company has partnered up with Clover to produce the new drink - and this was all part of their public relations campaign.

The advertising agency behind the campaign, Joe Public says images and videos of strange green lights beaming in the sky were created to gain traction on social media.

The agency's Adam Weber says the smouldering wreckage was a 'fun' concept used to position the drink as something from the future.

"We thought we'd pretend that a space ship was hovering around earth and crashed and in its pay load was this drink, the drink itself being from another future place."

The project started in Cape Town and moved onto Durban at the weekend.

It certainly got people talking, with the hashtag #UFOSA trending on Twitter with some quirky reactions from tweeps (that short for "Twitter people").

FutureLife's David Sweidan says he is excited to see the overwhelming response to the campaign.

"There have been some clever comments coming from all around. It's good to see the SA humour and we look forward to seeing how consumers actually react after tasting the product."

Sweidan has assured motorists that the crash site will not affect traffic and will remain at the intersection throughout the day.
