Yep the returning boosters are awesome . I did hear that the main booster ran out of fuel on its return run to its landing barg at sea. I think some outfit had been practiceing those landings on barges at sea, for some time.

Great technology for sure. To have the boosters being reusable.

I've also heard that it was not planned to go into orbit, rather head on out into space away from earth. I had not thought that they intended to separate the payload from the cargo bay?
Are those car in space shots supposed to be real?

There is a considerable difference in size and capability between the Saturn V and the small (relatively speaking) Falcon Heavy.

There is a good read here, and I think Ars Technica had a good one also.

Let's look at the basic statistics. The Falcon Heavy stands 230 ft (70 m) tall, its core has a diameter of 12 ft (3.66 m), and when fully assembled with its side boosters is 40 ft (12.2 m) wide and weighs 3,132,301 lb (1,420,788 kg). The Saturn V with its three stages in place, tops out at 363 ft (110.6 m) tall, has a diameter of 33 ft (10.1 m), and tips the scales at 6,540,000 lb (2,970,000 kg).

Of course, size isn't everything. The Empire State building is bigger than both the Saturn V and the Falcon Heavy, but it can't fly for toffee. On the other hand, the two-stage Falcon Heavy has nine Merlin 1D main engines in each of its first stage elements burning supercooled liquid oxygen and kerosene to produce 5,548,500 lb of thrust. Then the second stage takes over with its single Merlin 1D engine to punch 210,000 lb of thrust

That's remarkable when compared to the Atlas and Ariane rockets of today, but now let's look at the Saturn V. Its S-IC first stage has five Rocketdyne F1 engines that, when set loose, generate a staggering 7,610,000 lb of thrust as it burns kerosene and liquid oxygen.
