With a notion they might be able to find new undiscovered caves, a group of Irish cavers have attempted to attach a thermal imaging infrared camera to a drone.

Although they ran into a few snags with the extra weight of the FLIR ONE thermal imaging infrared camera equipped iPhone, they were eventually able to get some very encouraging images of the entrance Ireland’s Poulnagree cave. What’s more interesting is that they were able to get the images despite the cave sucking air in.

While this is not the first time this has been attempted, these results are some of the most encouraging we’ve seen.

We can’t wait to see the next video.
