The metre-wide Gloucester Old Spots pig set off for the capital from Mudchute Farm on the Isle of Dogs in the early hours of the morning, surprising commuters along the way.
As the drone-powered pig flew through the air, it delivered samples of Orchard Pig cider to people below.
The Somerset-based company will also be offering the brand’s cider throughout the weekend, courtesy of its pigs. Londoners can simply tweet @OrchardPig detailing what they’ve done that is against the norm for a chance to receive a cider delivery.
Andrew Quinlan, founder of Orchard Pig, said: "At Orchard Pig we believe that just because something is accepted doesn’t mean that it’s right. We are all told that pigs can’t fly so we chose to change this, the same way that people believe cider should be sweet and tasteless, we’ve crafted a drink that shows how great real cider is.
"We don’t want to stay with the norm because it’s comfortable. Our aim is to challenge perceptions and where possible we are going to challenge the status quo."
Back in May beer brand Brewdog dropped a series of taxidermy cats over London, to celebrate a crowdfunding record and the fact that businesses no longer need to rely on banks.
