Some additional observations, no idea if they're useful, other than possibly things people don't know?
1. Corrie chose to walk all the way from Flex up to Pizza Mama Mia. That's a dedicated walk, though I do understand making the effort to go your favorite kebab shop... Anyway, whilst the walk up is straightforward, he clearly chooses on his way back from Pizza Mama Mia to cross the road (to Brentgrovel) and head toward Hughes - basically, taking a different route to that he walked up minutes ago.
2. The police have had the rear Cornhill CCTV footage since at least Oct 5th. Described in the police 5th Oct update, the 3 teenagers are mentioned as being "being the Cornhill Walk center" who may have held information of activity "in Short Brackland". This means they were probably in the Cornhill staff car park, possibly taking a shortcut from Short Brackland to Well St (or vice versa). You can see why they might be reluctant to come forward initially, they were probably not really meant to be in that property, though it's clearly easy and not a big issue to use that as a shortcut. As you know, we have never been shown anything from the rear cam. However, with the teens being in that area at 4.20am, and with no other specific calls for people who were in Short Brack/Cornhill shopping centre staff car park, we can assume the camera either doesn't point at the road (so as to call on other witnesses seen walking or driving up/down it, of which we know of none) OR that there was no activity around 3.30am (Corrie's disappearance time). Or maybe means some other thing someone else can decipher.
3. There's a lot of activity around the 3.30am mark, with multiple people walking around the area. Yet you look at a time like 1.30am (eating kebab) and the streets look deserted. It's also interesting to note the interest in the "5am" unidentified people. I can understand wanting to identify people around the 3.30am mark, maybe even the 4.30am mark, but 5am? Well, I suppose... Anyway. We have Flex nightclub that closes at 3.30am (Corrie has moved away from this area). We have The Gym which is right next to The Grapes which closes at 3 or 3.30am (slim chance he intended to head over there after he'd eaten kebab at 2am?). There's also the Vision Nightclub on Station Hill that closes at 3.30am (though whether it's still running is open to question, I can't quite tell). It's not impossible to think someone may have left Vision once it closed to come down Short Brack and pick him up.
What I do feel this tells us tho, is that if there was any kind of horseshoe struggle, or if Corrie had walked home, pretty much in any direction from horseshoe, he would've been seen, by at least one or two people, but more likely by countless many. Yet no-one did. It seems 3.30am is a very busy time in Bury on a fri/sat night. 3 clubs all shut around the 3-3.30am mark so you've got people, taxis, traffic, police patrols... and CCTV shows that a LOT of people are walking around who would've seen or heard something in the direct vicinity yet never did. So IMO this practically rules out him walking away on foot or there being any kind of struggle in the horseshoe.
4. By terrible fate or co-incidence, a young girl aged 20 <modsnip> died just over a week later after Corrie's disappearance. I'm not saying it's connected, but that's not to say it's any less weird than Corrie. On 24th Sept a 23 yr old from Dumfermline "vanishes". On 5th Oct a 20 yr old from Dumfermline walks half a mile to a park on her own and keels over and dies (and is found at 7.30am). <modsnip> No publically disclosed info on her cause of death that I can find, it's not being treated as suspicious, but as I say, this girl obviously did not die on a night out with friends (ie hanging out in park late night) cos she was found at 7.30am by a dog walker, about 0.5 miles from home. But you have to wonder why she went walkabouts early in the morning or late at night, on her own, and then died in a park "unsuspiciously".

6. Corrie and his brother Darroch are clearly as thick as thieves (very close). I'm amazed Corrie would do ANYTHING and not let his brother know. <modsnip> I reckon Darroch is the one that's going to know best what Corrie is or was up to that night, his intentions, reasons for many of his actions that night, etc.
Some other notes. Press reported a lady reporting a
speeding silver car on Corrie's night. This was never mentioned again, what I just said seems to be literally the only description, nothing more, nothing less. Speeding where, speeding when? etc. Google "corrie mckeague speeding silver car" for source.
The silver car seen in horseshoe street view appears to be there in both the TV report with the man looking round the horseshoe, also the video with the grandparents. So as it's been parking in the same place since Oct 2015 thru til today, it's probably an employee car but I'd say it's one to keep in mind as one of the potential 3 in the area on Corrie's night. That said I do not think it's related to the one parked up in CCTV1, which appears to have different rear lights (red brake lights). Someone may want to doublecheck that (and as I say it may only ever be there in the day as all these sources are daytime images, so could be an employee who isn't there at night).
Probably of no significance, but in the grandparents video we also see a "bin lorry", which appears to be a food waste recycling truck. It might be worth considering if the larger bin lorries actually use this area or if they have to send in these smaller ones.
And PS. I was asked about the 3.26am CCTV Adnams image but I do not personally think that is Corrie with someone following him, sorry. Just 2 guys. Nor do I see the "Corrie behind some railings" in the bicycle image. The mind seeing what it wants to see in both those instances, I reckon.
That said, what we do now know now from that image is that The Grapes (CCTV 1 camera) clearly rotates to at least one other direction (St Andrews St North). I would not be surprised if it also looks back up Risbygate, so again at least 3 angles and certain black spots. The two CCTV cameras (kebab and alley) may never be looking in each others directions very often at all... Another thing is why we're shown the pretty crappy Adnams CCTV images when there's the Starbucks CCTV camera very close by.
