Falcon Heavy is late, but making Falcon Heavy economical means making all of the 3 F9 first stages it uses reusable. They haven&#x27;t cracked that yet, they&#x27;ve got 2 good landings and a lot of data, but it&#x27;s far from certain whether e.g. the landing attempt next week will be successful.<p>Most of their customers do not need the extra payload &#x2F; push of Falcon Heavy and so they&#x27;re concentrating on making F9 itself work first. This is reasonable I think.
