I was going to continue where I left off, but whoa there's been a lot of activity since then. Several pages worth.
Anyways, I found this interesting explanation on Quora, which explains more in detail how Bishop technically could have done it without playing the relativity of time in movies card too hard...
"" 1. He volunteers to remote pilot the dropship from the Sulaco. In doing so he provides an exaggerated timeline as to how long it will take to crawl down the pipe to the uplink tower, how long it will take to align the dish (come on... it takes an hour to align the dish!?), and the flight time of the dropship itself. This gives him the time he needs.
2. Using his extra time, he brings down the dropship, grabs a couple of eggs (found some along the way to the antenna or even went back to the Derelict), docks with the Sulaco and places the eggs in the ship and in the escape pod area to ensure that there will be at least one xenomorph survivor, and then flies back to the uplink tower to await the arrival of the survivors. The facehuggers, of course, do not attack him because he is not organic and therefore is not a viable host.
3. To cover his ruse, he remote pilots the drop ship into the air so it can be seen landing when the survivors arrive.
Because he must have surviving hosts for the facehuggers, he is diligent to tend on everyone's wounds, and save Ripley and Newt (even after he is ripped in half!). His motivation is never to benefit the humans, only to assure the survival of viable hosts for the eggs he has placed. ""
...Just wanted to share that.
In the end they should just cut out the egg from the opening sequence, or digitally alter its surroundings/placement on screen. It's an easy fix because walking/crawling eggs or good ol Bishop being yet another evil company android are not the kind of explanations we want because they seem forced and out of character based on what we've seen in the movies.
