326 reusable booster landings.
How many did NASA just drop in the ocean because they said it couldn’t be done?...............
None. SpaceX developed the Falcon 9/Heavy booster as a contractor to NASA. NASA developed the more or less reusable Space Shuttle before SpaceX even existed. Finally, reuse by powered landing probably couldn't have been done in the 1960s. Or '70s. Or '80s. Or '90s. IMO, it was done pretty much as soon as it was feasible.
On a different topic, of the 128 orbital launches to date this year, 81 have been American. 30 were Chinese. 8 were Russian. But America sux ... because groupthink said so.
