A streamlined craft with a single jet engine system has an airspeed of 2500 mph. On a ballistic trajectory, that's fast enough to send you 63 kilometers straight up from the highest altitude that your engine operates at (it should work above 15 km on Earth).

You can get into space without a rocket. Staying there is harder.

I don't think you can expect to get maximum speed going straight up, the weight of the aircraft offsets against thrust.

So put in a second jet.

Even subtracting 1G, 5 jet engines could lob you over the ISS while leaving room for an ion drive.

According to a design system with little correlation with reality, anyway.

Not contesting that, but munin's original reference was to SS6.
