And this is the exact reason that Starship hasn't "gone to orbit" yet. You just really don't want a vehicle this size in orbit without having the ability to control it.

As we know, New Glenn's upper stage failed to conduct its planned circularization burn; this left the payload in an unrecoverable low orbit. We have tracking data on the payload however, there is no data provided for the New Glenn upper-stage at this time. It's safe to assume it did not complete a disposal burn. New Glenn upper stage and payload will re-enter within the next 4-5 days. New Glenn upper stage dry mass is around 25 metric tons and measures in at ~ 77ft x 23ft which is comparable to the Long March 5B stage that the CASC left in orbit a few years ago. New Glenn's upper stage poses a significant risk to locations between 36.11 degrees N/S latitude and will generate a large debris field. If it re-enters over land, largely intact pieces may be found, possibly as large as 5 feet or more in diameter. Lighter-weight spherical objects such as COPVs are expected to partially/completely survive re-entry.

UPDATE: The SpaceForce has released tracking data for post-SES-2 time, it does appear that ignition occurred; however, it only completed about half of the intended orbit correction. This does increase the on-orbit estimation time. Something closer to a few months. Perhaps re-entering close to late June, early July? This orbit should in theory, be recovered from just at an extreme deltaV cost by the BluBird satellite. So with that being said, its now closer to 43.0 degrees N/S that are at risk and not 36.0
