Google has announced a program developing an army of flying drones that will deliver packages to people’s homes.

The program, known as “Project Wing,” will compete with Amazon’s drone fleet, which is already carrying out test-runs to customers of the online store.

Exactly what Google’s drones will be delivering is unclear because, aside from Google Glass and a few other gadgets, the tech giant doesn’t exclusively sell many physical products.

The impression is that you’ll be able to select the drones as a delivery option whenever you make an online purchase (except from Amazon and other competitors) or mail something, with the package set to arrive at its destination on the same day shipped.

Project Wing’s price tag remains unknown.

According to NPR, Google estimates a few more years will go by before the drone fleet is ready, but the company says test flights successfully delivered a first aid kit, dog treats and some candy bars over the distance of half a mile to farmers in Australia two weeks ago.

Google and Amazon both need government approval to fly drones for commercial use, a step Amazon has a slight lead on considering it already asked the Federal Aviation Administration for permission to expand the limits of its test flights last month.

The drones will be made in Google’s “X” laboratory, which is also working on self-driving cars, balloons that will supply third-world countries with Internet access and contact lenses that monitor glucose levels in diabetics and provide close-proximity sight for the visually impaired.
