[32] At that time, the "solid surface" was not further described, and was later revealed to be a seafaring barge dubbed an autonomous spaceport drone ship. [83], On June 15, 2016, Falcon 9 flight 26 successfully delivered the Eutelsat 117W B[84] and ABS 2A[85] satellites into GTO.

There are two possible answers to this, although you probably won't like either of them.

@Daniel I know they had to fly tilted because of the offset engine, but it seems like any adequate landing gear meant to be reused should be able to handle that kind of stress without being permanently crushed. Improper control of subcooled-LOX temperatures
[18] However, the stage began to roll because of aerodynamic forces during the atmospheric descent and the roll rate exceeded the capabilities of the first stage attitude control system (ACS) to null it out. Space
[11] Then, shortly before hitting the ocean, one engine would be relighted in an attempt to reduce the stage's speed so that it could be recovered. The rocket was "able to successfully transition from vacuum through hypersonic, through supersonic, through transonic, and light the engines all the way and control the stage all the way through [the atmosphere]".

The boost-back burn limits downrange translation of the used stage; the reentry burn (from approximately 70 to 40 km (43 to 25 mi) altitude) is used to control the descent and deceleration profile at atmospheric interface; and the landing burn completes the deceleration from terminal velocity to zero at the landing surface.

I'd say that with prep including software modifications, the F9 could probably land in a salt-flats desert but not on any unprepared Lunar or Martian surfaces. Every Starship that has flown so far (Starhopper, SN5, and SN6) had different landing legs (and neither of the three had landing legs that matched any of the presentations, although Hopper was at least somewhat close), and Elon Musk has just tweeted last week, that they will be completely changing them again.

SpaceX continued to return a number of first stages in both ground and sea landings to clarify the procedures needed to re-use flown boosters.

What would the damage radius be if a Falcon 9 booster impacted the Earth without a landing burn?

That caused the engines to shut down early while the first stage was just above the drone's deck, causing a landing failure.

The research team is particularly interested in the 70–40-kilometer (43–25 mi) altitude range of the SpaceX "reentry burn" on the Falcon 9 Earth-entry tests as this is the "powered flight through the Mars-relevant retropulsion regime" that models Mars entry and descent conditions.
