Default Successful SpaceX launch

When I studied rocket propulsion at the Ohio State University, under Garvin vonEschen, he said it took a few losses for them to come up with the idea of a hold down clamp to hold the rocket in place until full thrust was attained. Prior to that time, they'd light the engine, thrust would run up, and there was a time when thrust just equaled weight - and if it was a calm day - well, everything would go well. If there was a strong breeze off the Baltic Sea, the rocket would drift and most likely run into something before it cleared the ground.

I suspect there is another version of the hold down clamp for landing rockets that is awaiting development. One that will locate the rocket and grab it securing it to the landing platform.

Also, and likely the most historic, the first stage landed successfully
on the barge, which is a first!


I managed to get online to see the youtube-carried technical feed.
How long does the stage just sit there bobbing in the ocean with the
barge waiting for a rogueish wave to come along and upset the apple
cart?
