         | From what I've gathered:
         | 
         | They should have enough satellites in the sky, at the right
         | positions, to start offering limited service around the start
         | of July. This is based off of Elon's statement that they need 6
         | launches worth of satellites, educated guesses on launch dates,
         | assuming that satellites need to move into their operational
         | positions after that 6th launch, and will take the same amount
         | of time to do so as previous launches.
         | 
         | They hope to be ready to help out with emergency service
         | connectivity this hurricane season, which starts roughly
         | speaking in August. That gives them around a months buffer,
         | which sounds reasonable.
         | 
         | They don't seem to yet be making huge moves to get ground
         | stations up and running, advertising to consumers, etc. This
         | leads me to believe that the initial service will not be
         | consumer oriented (probably as they work out the kinks). We
         | know they're interested in emergency services, and we know the
         | military is interested, these are likely to be higher paying
         | and more forgiving customers to start with since they aren't
         | competing with traditional ISPs at all. For them, somewhat
         | unreliable service is better than no service.

             | reasonable-ish (eyeballing at >80%) uptime across most of
             | the world provided they can get ground stations.
             | 
             | They'll continue to launch satellites past the first 6

             | the end of the year compared to a June or August launch.

             | and the proposed Starship fairing would be 9m diameter by
             | 19m high. SpaceX is currently proving they are capable of
             | sustaining a rapid launch cadence and have already proved
