“I'm not angry because my flight was cancelled. It's a pain in the arse but what really infuriates me is the "We are terribly sorry" these PR releases give... when words have no meaning behind the phase.”

Just had to cancel my 10-year passport renewal appointment for tomorrow morning, since it's in London and I'm in the EU. Man, this was a *miserable* way to spend a day. The flight kept getting bumped, heading for certain cancellation (it came, about midnight, long after I had returned from the airport); GPT was incredibly helpful on how to redeem…

People are linking this UK airport meltdown (8 Sep 2026 22:04 UTC) to Israel's statement: "it has left us no choice but to respond to its hostile actions". (8 September 2026 at 16:55 UTC) The timing is really curious. The scary thing is that Israel has advanced level of cybercapability and total deniability. 🙁 https://www…

Currently stuck at an airport in london. It's insane how little information the staff here has. Also mindboggling that in aviation, where everything has a backup or two there seems to be a single company with a single software that can take down an entire airspace which most like will create worldwide ripple for the next days.
