I wonder how much money they will spend before the system is operational and can provide residential service?

Only 499 launches to go!  At the current rate of 2 launches per year they will be fully operational in only 250 years.  LOL.

Nah. They plan on increasing the frequency of launches dramatically next year. These first few are really more for testing than anything else.

Not as if Exede didn't have a lot of issues when it came online too. If was probably over a year before it became stable.

When I hear 10,000 satellites, or even 30.000, as mentioned, the first words that come to mind are space junk.

So, if one senator stays in Washington, D.D. during Christmas break you would consider the senate to be “up and running?”  You must be in marketing!  LOL.

I would hope they could get 610 Mbps to one airplane.  That means 10 airplanes in that area would get 61 Mbps each.  Figure 100 passengers on each plane and they will get a whopping .61 Mbps each.  Yippee!

Despite your feeble attempt at sarcasm, YES!  Especially if it is YOUR senator.  It is obviously not working at capacity, or providing 100% of its desired operations, but upon arrival of the senators it is a functional entity, as opposed to, designs, approvals, funding, ground breaking, construction, etc.  If you are restoring a car it is a milestone when it is "up and running" you turn the key, it starts, and goes down the road under its own power.  It may be years completing the detail work but it is still "up and running" regardless.

610 Mbps, at 300 MPH the entire area of coverage with no loss?  Yea that impresses me.  How do you assume 610 Mbps is the limit of the beam and not the receiver or device?  It might even be the limit of the program used for the testing.  Now lets suppose 100 people on an airplane all have laptops and all are downloading the latest version of Windows all at the same time (SMH) whats wrong with 0.61 Mbps?  Thats higher than what Viasat expected me to run on half the time and called it "high speed".  Much of the time I was below 0.5 and peak usage under restriction it was more 0.05.

Maybe available in late 2020 to some customers.  Anyway for those that won't get a ground based ISP under the governments program to bring everybody on line this will offer another alternative.

Speaking of that. The government's expectation is a minimum of 25Mbps down and 3 up. That would be the average of course. Viasat cant deliver that nationwide today. More pressure is coming down if you cant deliver that, no grant money will be coming, and Viasat likes its grant money (what business wouldn't).

So “ground stations” aren’t “land based.”  That is interesting...

One large problem with LEO is that one EMP from a rogue nation like North Korea could take out a huge part of the constellation in an instant.  Optical fiber is immune to EMP.  And if you think that replacement of defective satellites won’t be based on the revenue potential of each satellite, you are quite naive.  Satellites that serve sparsely populated areas will get the lowest priority for replacement and very likely would get shifted to a different orbit if needed to better serve more highly populated areas as needed.  Just as with land-based systems, repairs and upgrades will absolutely be prioritized based on the per satellite revenue.

WHO CARES if the cable is immune if everything connected to it isnt?  The cable doesnt "do" anything it is merely a conductor.

How do you come up with prioritization based on revenue to a satellite grid?   Landlines coming to my house serve MY HOUSE, my signal from a satellite serves thousands.  First off area of coverage is greater so there is a better mixture of use and a similar balance of revenue on most beams.  Yea I am in the sticks, but my "beam" could cover 6 or more cities around me, my satellite many more still.  Hardline is fixed.  Depending where the problem lies they have a definite number of customers affected and can base the priority based on that info.

It is hard to explain things to someone with so limited an understanding of the systems in question.  LEO satellites don’t sit in one spot.  They orbit the earth at a rate far faster than the earth’s rotation.  It is almost certain that the satellite constellation orbits will be designed to provide much denser satellite coverage for parts of the world that have the highest user density.  And when satellites begin to fail, and they will with 10,000+ in the constellation, you can bet that the replacements launched will go first into orbits that provide the most coverage of high user areas to maximize revenue.

That is not fundamentally different than how an electric utility prioritizes their service restoration activities.  If you can send a crew to a location where 2 hours work restores 1,000 customers rather than a location where 2 hours work restores 10 customers, any logical person will prioritize the former location above the latter.

And LEO satellites need a lot of ground stations, especially in high density areas as most satellite users won’t be talking to other satellite users, but will need to get onto the land based internet as quickly as possible.  And these ground stations will also have outages and their restoration will also be prioritized by the density of traffic carried.

Constellation design for non-GEO satellites is not trivial.  https://www.astrome.co/blogs/the-art-of-satellite-constellation-design-what-you-need-to-know/

Quick rundown:
April 10, 2019
Tesla catches fire
Crews try to cool it for 3 days
Relocated for security purpose 
Tesla says they will dispose of it but don't 
Tesla homepage says ÖCAR Automobil Recycling will get rid of it 
ÖCAR has no permission to handle Tesla wrecks
Tyrolan waste disposal companies refuse to deal with the car
DAKA expert cannot deal with such a big lithium battery without knowing chemical mixture
Tesla keeps it a secret for competitive edge
The fluid that cooled the car is a dangerous poisonous mixture but sought-after 
Montana University has secured probes to find out the ingredients of mixture 
Professor says he doesn't know how to dispose of car or its 600kg battery 
Professor criticizes Tesla for inventing a product without thinking about its disposal 
Tesla still has done NOTHING about it

BUT THEY ARE GOOD FOR THE ENVIRONMENT!

@Ron You seem to think that every satellite orbits past your house.  That ain’t so.  The density of satellites in a constellation does not have to be uniform as with GPS.  It can be very dense in some locations and barely enough to see two at a time in other locations.  So, the revenue per square mile of earth surface is not uniform just as it is not uniform with land based systems.

If LEO satellites of which I know nothing about orbit at a speed different than the Earths rotation & there are going to be 10's of 1,000's of them out there what keeps them from being a traffic hazard to manned space travel?

I wonder if political pressure may become the biggest obstacle at some point.

This has been discussed before. I believe the demand for better internet to the under served masses will supersede political obstacles.

Dont count on it. People protest about anything, including wind power because it obstructs a view and/or kills birds.

Supposedly they have a plan to deal with all the extra satellites in space. Last I read though is that nearly a third of all the satellites currently in space are "dead" and basically floating junk.
