Ann: 3 Diamonds Launch Date Confirmed May 2017, page-39

It was apparently pencilled in for April but always subject to final confirmation and likely to change.

Late May suits me fine as my first bundle turns 1 on May 31 so I'll be tempted to jetison stage 1 and free carry the rest into the stratosphere, or whichever sphere 500km is in. I'm sure I'll be taking the night off work when the date is finally settled, subject to clear weather.

This is going to be a ripper.
