I had a similar thought about watching it crash down into the Pacific off of Hawaii. If it makes it that far, they plan to sink it in a naval graveyard about 50 miles north of the island. Watching it attempt to soft landing and then sink below the waves would be remarkable
This second stage is going to slam into the water at terminal velocity (per FAA filing). No mock landing flip and burn. The two after will break up on re-entry (no "wings", people suspect they are for payload or propellant transfer tests).
The booster, however, will do a mock landing over the water a ways out from the launch facilities (40 miles I think it was).
