We’ve got a late departure ourselves this week since our update is published day later than usual. Well, even we aren’t faultless, hey? Here’s what we have for you from this week’s airport news around the world:

• London’s ‘Boris airport’: the next chapter
• Chicago’s alligator ‘delivery’ caught on camera
• Weapons that can be made with airport purchases

The first news we’re covering also came in right at the start of the week when on Monday more details about the proposed Heathrow replacement airport, dubbed “Boris Island Airport” was revealed. Together with its official name, London Britannia Airport, the BBC published the news from the press conference by stating that the proposed six-runway airport formerly known as Boris Island, would cost £47.3bn and that the consortium behind the scheme claims it could be built within seven years. A spokeswoman from Testrad, the consortium behind the airport’s plans, was quoted in the article saying that a key point was “separating people from planes” by giving passengers the benefit of air travel but without noise because all aircraft landing and departures would be over the estuary rather than residential areas. You can read the full press release here.

Remember our alligator story from last week? Well, in short a small alligator was found under an escalator at Chicago’s O’Hare international airport (ORD) and had left authorities puzzled. This week a security video revealed the suspect. Sky News wrote that the CCTV images released by the Chicago Transit Authority appear to show the woman holding the 2ft reptile on board a CTA Blue Line train a few hours before it was found at the airport.

It was also confirmed that the gator, which has since been named Allie, was placed in the care of the Chicago Herpetological Society, where the group’s president Jason Hood said it has “not responded well to food”. We certainly wish it well, little Allie!

Then later in the week we received news we didn’t really want to tweet about initially. The Blaze, an online magazine, wrote about a YouTube channel that covers weapons that can be made just with items bought beyond airport security. In our view the troubling bit is the detailed way the video blog describes the making of these weapons. Judge for yourself and let us know what you think.

That’s all for this week – safe travels!
