Coming Up With A Plan
With help from Jar on the back-end, The Peacock impersonated a Night Corp employee and called into Militech's logistics division, asking for plans for the tower because they were getting a new set of automated garbage trucks and needed precise measurements. Plans in hand, Paxos and Specter analyzed them, looking for weak points and places suited for long-term habitation where they might be storing Mary-Jane, The Peacock's sister. Two places stuck out: animal pens (used for live ammunition tests, naturally), and some of the security holding cells about halfway up the tower.
Typically, the cells were for relatively short-term while they worked out extradition treaties with whichever company's agents had been captured (mercenaries like the crew would simply be killed). In terms of alternate entry points, there were multiple AV landing pads at different heights, rather than a single hangar, and the "gorilla chute" which let out waste from the animal pens on the fifth floor. They also learned some fun facts: at 71 stories aboveground, it is 1 higher than Arasaka Tower. After its construction was completed, a city ordinance was passed banning construction over 69 stories.
Figuring flying in on AV sounded better than the gorilla chute, they started looking into them. Jar looked into the specific models that were in use so they'd blend in, while The Peacock reached out to, Kei Honda, a certified pilot they knew who flew under Airs United, one of many fly-by-night (literally!) companies that existed to ferry executives who felt being driving to work was below them. Kei wasn't working with Militech at the moment, but to give them a start she knew a company that did: 1776 Holdings. Specter went dumpster diving outside their offices to see if they'd thrown out anything interesting, but got distracted instead and didn't find anything.
