Alphabet's Project Loon Delivers Internet To 100,000 People In Puerto Rico (engadget.com)
Google announced that its Project Loon internet balloons have delivered internet service to over 100,000 Puerto Ricans who were knocked offline by Hurricane Maria. Engadget reports: It's not a total success, which isn't to be expected after Puerto Ricans' communications infrastructure suffered so much damage. But the team was able to work with AT&T and T-Mobile to get "communication and internet activities like sending text messages and accessing information online for some people with LTE enabled phones," head of Project Loon Alastair Westgarth wrote in a blog post. The team launched their balloons from Nevada and used machine learning algorithms to direct them over Puerto Rico, where they've been relaying internet from working ground networks over to users in unconnected areas. In the post, Westgarth noted that Project Loon has never fired up internet from scratch this rapidly, and will improve their ability to keep balloons in place (and deliver sustained connectivity) as they become familiar with the air currents.
Loon balloons navigate by changing their altitude to reach winds that are going in the right direction. They know what the wind directions are by modeling the atmosphere in the 18 to 25km range. It's rather ingenious.

The balloons are maneuvered by adjusting their altitude in the stratosphere to float to a wind layer after identifying the wind layer with the desired speed and direction using wind data from the National Oceanic and Atmospheric Administration (NOAA). Users of the service connect to the balloon network using a special Internet antenna attached to their building. The signal travels through the balloon network from balloon to balloon, then to a ground-based station connected to an Internet service provider (ISP), then onto the global Internet.

Project Loon is Google's pursuit to deploy a high-altitude balloon network operating in the stratosphere, at altitudes between 18 km and 25 km. Google asserts that this particular layer of the stratosphere is advantageous because of its relatively low wind speeds (e.g., wind speeds between 5 and 20 mph / 10 to 30 km/h) and minimal turbulence. Moreover, Google claims that it can model, with reasonable accuracy, the seasonal, longitudinal, and latitudinal variations in wind speeds within the 18-25 km stratospheric layer.
Given a reasonably accurate model of wind speeds within the 18-25 km band, Google claims that it can control the latitudinal and longitudinal position of high-altitude balloons by adjusting only the balloon's altitude. By adjusting the volume and density of the gas (e.g., helium, hydrogen, or another lighter-than-air compound) in the balloon, the balloon's variable buoyancy system is able to control the balloon's altitude
Then again the Japanese were able to direct fire balloons through the stratosphere all the way to the US with no computational power at all in WWII

The balloons didn't do any real damage to the US, but the Americans were worried about biological or chemical weapons being used in the future. So they covered up the fact that the balloons were successfully reaching the US mainland.

The bombs caused little damage, but their potential for destruction and fires was large. The bombs also had a potential psychological effect on the American people. The U.S. strategy was to keep the Japanese from knowing of the balloon bombs' effectiveness.
In 1945 Newsweek ran an article titled "Balloon Mystery" in their January 1 issue, and a similar story appeared in a newspaper the next day.
The Office of Censorship then sent a message to newspapers and radio stations to ask them to make no mention of balloons and balloon-bomb incidents. They did not want the enemy to get the idea that the balloons might be effective weapons or to have the American people start panicking. Cooperating with the desires of the government, the press did not publish any balloon bomb incidents. Perhaps as a result, the Japanese only learned of one bomb's reaching Wyoming, landing and failing to explode, so they stopped the launches after less than six months.
The press blackout in the U.S. was lifted after the first deaths to ensure that the public was warned, though public knowledge of the threat could have possibly prevented it.
Prior restraint has its uses, even in the USA.

I think the implication is that some AT&T and T-Mobile towers are online BECAUSE they were able to leverage Loon to connect, i.e. your cellphone itself wouldn't be working in areas without it.
I'm currently on San Juan Puerto Rico. I don't know a single person who have receive internet from project loom. To the the 100k, is unreal, just a way the project has field.
How would you know if your phone is connected to a balloon vs a tower? Maybe you posted via a balloon.
