A Qantas Airlines flight that left from Perth, Australia, on Monday night
returned to the same city the next morning after more than 15 consecutive hours in the air
— thanks to turmoil in the Middle East.
The flight, QF33, which was supposed to land in Paris,
was among a number of airplane journeys that were disrupted
after attacks in the region involving the United States, Israel and Iran prompted officials to temporarily close air space in the region.
Pretty sure my mom gets that “flying-an-airplane-without-a-manual” feeling whenever she walks in and catches sight of my anarchist flag waving next to the rainbow, trans, and neurodiversity pride flags.

So Via Rail charges you if you want seats that are not rear facing.. but even when they do, they often do not honour the seat assignments.
Great.

Good Morning #Canada
For over 20 years, this 17-meter tall musical instrument has struck a chord with visitors to Sydney Nova Scotia. This installment of #BigStuffInSmallTowns showcases the biggest fiddle in the world and is a must stop selfie spot for cruise ship passengers as they disembark at the harbourfront. But Sydney has a reason to fret about their fiddle dominance as the original artists has been asked by two other towns to create an even bigger version to take the world title.

On my way to The Hague, to draw the red line for Dutch government with respect to Israel's continuing genocide in Gaza.
After last time's 100,000 participants, NS put in a lot of extra trains. My very early one already has a lot of passengers in red.

The difference between the passengers on a doomed plane and Joni Ernst is that the passengers say "We're all going to die! We're all going to die!" 😱 😱😱 while Joni Ernst says "We're all going to die! We're all going to die!" 😃😃😃

En Route Path-planning for Partially Occupied Vehicles in Ride-pooling Systems

It is fascinating how the electrification of public transport buses is also creating new business and collaboration models: First Bus already opens its depots during the day (when the buses are in service) to pre-approved parties, such as fleets of buses and trucks, and is now also launching #EV charging hubs for everyone (9 a.m. to 4:30 p.m.), as “First Charge”, as in Glasgow (34 x 150 kW).
Think I'm done for today. Got to level 4, only killed a couple of passengers, and now I can go for my CPL. I'm going to wait for the new sim gear to come in because my space sim setup doesn't translate well to flight sim duties. However, MSFS has great so far.

Spotted a Tesla Semi truck in the wild, pulling out of the Tesla lot onto Page Mill Rd. Driver in green safety vest sits in the middle of the cab (no passengers?). While stopped at a light it looked like the driver was fighting with trim falling off the left A pillar.
A few blocks later the truck blew through the red light! Particularly scary if Tesla's AI was "driving".

A Gaza-bound aid boat carrying Greta Thunberg and other activists arrived at an Israeli port Monday after Israeli forces stopped and detained them
Israel’s Foreign Ministry published a photo on social media of Thunberg after disembarking.
The 12 activists were expected to be held at a detention facility in Ramle before being deported, according to Adalah, a legal rights group representing them

So, completed the first flight with the new controls. They are _significantly_ different than the setup that I have for _Elite: Dangerous_ which isn't necessarily a bad thing. Once I managed to get used to the control scheme the flight was pretty smooth.
Unfortunately I'm gonna need to practice landing and using the rudder pedals a lot because the landing was one of the absolute worst yet. The passengers were not amused, but since we all lived they should be grateful.

#EndFossilFuels #ClimateAction
Fact: Taking a BC Ferry from Metro Vancouver to Vancouver Island is a High CO2 experience, though if it's a full ferry, it's not terrible (~5kgCO2/passenger)
By 2031, BC Ferries will have replaced 18 ferries (big and small!) in 15 years, and nearly all will be 100% electric-ready.
They just announced they're doing the big ships next.
"Built with diesel-battery hybrid propulsion systems and designed with the capability to operate on full electric power in future, the NMVs are expected to significantly reduce greenhouse gas emissions, improve fuel efficiency, and lower underwater radiated noise to better protect marine life. With greater capacity than the vessels they replace, the NMVs will offer more space for vehicles and passengers and upgraded amenities, supporting a more reliable and comfortable travel experience.”
The age of fossil fuels is ending. Any politician or lobbyist who says otherwise is either not paying attention, or bought.
