Both must be on solid ground or a landing ship, mostly intact, and stationary, on the same flight. Starship must have flown to over 100 km on that flight.

For details, this question will use the same criteria as these:

/chrisjbillington/will-spacex-land-a-spaceflown-stars

/chrisjbillington/will-spacex-land-a-super-heavy-boos

/EvanDaniel/which-happens-first-starship-superh

Answers are for "on or before flight number X", so if they succeed on flight 11, then answers 11, 12, 13, etc. all resolve Yes, regardless of the outcome of flight 12.

I'll add more answers as future flights approach, as indicated by prices on existing answers.
