During a webinar on Thursday, analysts from the firm outlined the reasons why they think SpaceX has been able to achieve a positive cash flow in its space Internet business just five years after the first batch of 60 satellites were launched. The co-founder of the firm, Chris Quilty, said the rapidity of Starlink's rise surprised a lot of people, including himself.
