Instead of trying to land their stage on the barge next attempt, they should track down that boat and attempt to land on that.
I like that. I like that a lot. Burn it. Burn it with fire.

The fouled range KEEPS HAPPENING! This is a recurring problem at Cape Canaveral.
They should start using the sound weapons that are used to deter pirate attack.
Guns make sounds...if you're the target.

SpaceX needs to supply extra insulation to the chilled LOX tank or supply chilling equip to it. There is no way a 10 minute hold should make the vehicle unflyable.
But it is technically simpler and cheaper, to just replace boil-off losses with cold LOX from storage until engine start (like it is also done by the Ariane 5 ECA). And that simply works only as long as you have LOX on the launch site.
10 Minutes are no problem. 50 minutes are the limit right now. You could of course clad the rocket with insulation bricks that should fall off during launch (like it was done on the Ariane 4, which launched in much hotter climate).

Didn't see the launch. I thought it was only a 10 minute hold in this case?

No, this time it was a short hold because of a range safety violation (Boat in the first stage landing zone), followed by a T-0 launch abort after engine start.
After the launch abort, the launch attempt was scrubbed for cycling back and investigating the cause of the automatic launch abort.
The implication of the Elon tweet seemed to be the short hold was the cause of the abort, implied also to be over-pressurization of the LOX tank.

No tweets here. See also: "Things that Elon said"
EDIT: From what I can tell about his wild tweeting, the possible helium ingestion into the engine is the far worse problem because it should absolutely not happen at standard gravity.
If the short hold due to a range violation had no impact on the launch abort then it really would not present a serious problem. You just hold for the short time, then launch after the short hold.
I get the impression that even short holds present a problem for the superchilled LOX.

Launch set for Tuesday at 6:46.
