Flynn, an ardent libertarian, thought that as early as the turn of the millennium, private industry would be ready to offer all kinds of spaceflight services that the general public would rush to buy, such as FedEx delivery anywhere on Earth in 90 minutes.
Right now, there's simply no market for that kind of delivery, and launches are not able to be set-up and made in that short of a duration either.
There's literally almost nothing on this world that is both so unique as to exist singularly and so instantly-needed potentially anywhere to justify the expense of launching that one thing into a suborbital flight on a rocket for delivery. Between warehousing of goods and relatively rapid transport of things by-air, just about anything the size and mass of a car can be transported to anywhere in the world in about a day.
If there were a market for delivery faster than that, I would expect surplus military supersonic jets would take up that market. Get something the size of a human being anywhere in the world in under twelve hours.
Unfortunately we can see how supersonic really isn't in demand; the Concorde never saw its fleet expand beyond its initial, tiny order, and when it was retired from age and design flaws rearing their ugly heads there was nothing to replace it. If anything would justify instant transportation it would be passengers, not cargo, and if there simply aren't enough passengers to keep a fleet of fourteen flying, then I don't see how Flynn's dreams were in any way close to reality.
