That's the 1st 3rd of the story.

Here's the 2nd 3rd.

The EC145 helicopter flew over to St Barth. 3 people got off and went into the terminal building. 10-15 minutes later, 3 people, perhaps the same 3 people, came out and re-boarded the EC145. The EC145 took off, and probably returned to SXM.

Back to jrr or whomever for the rest of the story.
