Having read the explanation of what was intended (listen in to communications), I was going to interpret "Hide and Hijack" as being functionally the same as "Hide and Observe", so in this case it does indeed not make a difference.
That being said, it's probably best if you try be as unambiguous as possible so that I don't accidentally interpret your plans in a different way from what you intended.
You have science level 5 and tech level 3 light industry, which (as previously stated) includes the ability to produce tech level 3 pharmaceuticals. I'm sure your people can find something that works as a tranquilizer. Of course, actually getting that tranquilizer into your targets' bloodstream is a bit more difficult. You could probably improvise some kind of signal jamming as well.
I'll make a note that you're interested in capturing the dropship's crew and take it into account when writing the next update.
