Attempted crewed SpaceX flight prior to 2020?

It was previously asked whether there would be a crewed SpaceX flight in 2018. Given that the first launch of the Dragon V2 (SpaceX's first human rated vehicle) is slated for a first crewed flight in April 2019 (as of the writing of this question) and that flight schedules are only extremely rarely moved forward, that question will almost certainly resolve negatively.

Yet, it is unclear whether further launch delays will push the date of the first crewed test-flight even further into the future, perhaps even beyond 2019.

It is asked:Will the first crewed SpaceX (test) launch take place prior to January 1st , 2020 at 00:00 UTC?

Should the rocket engines start before the above mentioned time, and lead to a launch that brings the crew to a height of at least 1 km alive, this question will resolve positive. Else negative. Safe return/survival of the crew is not required for positive resolution.


Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
