Am I going mad I only see two booster landing in the video?

On the live stream, the video feed cut out for the landing of the third (middle) booster.

This almost always happens. It's really hard to keep a stable satellite connection, while a 150ft. booster is blasting the deck with the exhaust from 3 firing rocket engines.

Not only that, but apparently they recovered both fairings: https://www.google.com/url?sa=t&source=web&rct=j&url=https:/... So 5 out of 5...

I guess salt water isn't that much of an issue after all?

Developing the recovery process has given them the chance to examine multiple fairings after they landed in the ocean. I'm sure they took the opportunity to see what refurbishing them would take, and perhaps that's what informed this decision.

I was at Kennedy Space Center's Apollo/Saturn V viewing site for this launch and it was amazing. If you ever have the opportunity to be there for a Falcon Heavy launch, do yourself a favor and go. It's quite an experience and totally worth the money.

What was amazing about it? Tell us the story.

Yea, I wish we'd get a more detailed explanation of the accounting on this. For all I knew it was totally plausible that fairings would be destroyed by sea water, and it was also plausible there'd be no damage. The part that confuses me is why they would spend so much effort trying to catch them with Mr. Steven if they are in fact serviceable after a swim. Maybe the idea is that salt-water refurbishment-and-reuse sav…

There was a sibling comment which mentioned some kind of anti-salt-water treatment, I guess that was Plan B and crossed the finish line while Plan A was still struggling?

It doesn't fire all three engines down to the deck. The landing burn starts with one engine (in order to have more control authority when the two outboard engines start up), then two more engines get lit, then they shut down shortly before the actual landing (reducing the TWR makes the landing a bit easier).

I've seen a falcon launch (not the falcon heavy). It is indeed amazing

I think that is only an issue with hard to clean equipment, like engines.

SpaceX thought it was enough of a problem for the fairings that they built a boat [1] to catch them before they hit the water. Either they've redesigned the fairings or they've re-evaluated their post-recovery process to make it possible to reuse fairings recovered from the water.

I wonder what emergency procedure is in place in case the landing is off-course. Does it blow itself up?

As an addendum to that, if one accidentally lands in my back yard, can I keep it?

Probably not, but maybe you could fine them for littering. http://mentalfloss.com/article/70708/nasas-unpaid-400-litter...

Can we finally stop having sci-fi films in which the whole outcome of the movie is solely determined on some heroic manual flying of a spaceship while simultaneously using manually aimed weapons like it's World War II?

The Apollo 13 astronauts would like to share a couple of anecdotes with you.

Apollo 13 (the movie) had plenty of careful checklist readbacks and minimal explosions or shaky cameras. Most scifi is more like Michael Bay in space. See Gravity for a more egregious example of a movie that tries to play itself off as "hard scifi" but ends up just being an over the top action movie.
