A couple of years back when NZ's first space-launch company, Rocket Lab, started up, the first launch date & time was notified to all authorities concerned, but Maritime Safety forgot to put it out on a Notice to Mariners.
When the first commercial rocket lifted off from the end of the Mahia Peninsula in November 2017, the cement ship 'Aotearoa Chief', was right underneath it, heading for Napier! If the first stage had failed, the AC would have ended up with extra 'deck cargo!
Because they didn't know about the launch, none of the crew were on deck to watch it!
Rocket Lab have now done 23 launches and put 109 satellites into orbit so far.
And haven't hit any ships yet!
