UPDATE 15:27 BST: Singapore Airlines told IBTimes UK that the AirDrop stunt definitely didn't happen. "Our pilot was only replying in jest to the radio message from the captain of the other flight. Photos were exchanged by email later, however," a spokesperson said.

A cargo pilot is claiming to have wirelessly transfered photos across 1,000ft from one aeroplane to another in midair, in a video that is now going viral.

Jamaican Aviation Spotters, a hobbyist community of plane watchers, has posted the video on Facebook, in which a US cargo pilot flying a Boeing 747-8 jumbo jet at 35,000ft attempts to send photographs from his iPhone to the devices in a Singapore Airlines jetliner.

The pilot records himself from the cockpit, showing that a Singapore Airlines Boeing 777 is flying about 1,000ft above his aircraft. He pans the camera to show himself adjusting a setting on one of the cockpit's control consoles, then uses the radio to makes contact with the pilots of the Singapore Airlines flight, identified by the code 'Singapore 12'.

The cargo pilot tells the Singapore Airlines pilots that he had some photos of the jetliner taken from below, and he says he wants to AirDrop the photos to the other aeroplane.

It is not possible to tell if the Singapore Airlines pilots assented to this request, but the next shot is of the pilot's iPhone apparently sending images using the AirDrop tool to a device identified as "SingTriple7".

The video appears to show that the photos are sent within a few seconds, after which the Singapore Airlines pilot is heard saying, rather indistinctly, "We appreciate your AirDrop."

But did it really happen?

As of 3.30pm BST, the video post has so far been shared over 9,000 times on Facebook in 12 hours and viewed about 7,500 times on YouTube. On Twitter, the video has been retweeted 1,900 times. However, many viewers are sceptical and think that the video might be fake.

One point of contention is the fact that in the video, the cargo pilot's iPhone is clearly shown to be in Airplane mode, and only Bluetooth is enabled. Add to that is the fact that Apple itself says that the range of the AirDrop function is only about 30ft, and if you want to use the service, you need to have Wi-Fi enabled at the same time.

So if the iPhone wasn't connected to the aeroplane's Wi-Fi and the other aeroplane was 1,000ft away, how could it be possible?

And maybe it's just us, but at IBTimes UK, we often struggle to get AirDrop to connect properly on two iPhones sitting side by side, or an iPhone sitting next to a MacBook – let alone 1,000ft away in mid-air, when both aeroplanes are travelling at high velocity.
