Reply to Bye-bye airplane mode: EU allows smartphones during flights by Zhukov-74

As a result, 5G coverage can also be made available on aircraft.

It's ridiculously expensive for many airlines and airports to switch over. There are old Boeings out there that still load software from floppy disk.

The reason we have people in airplane mode was there was a fear of detonating devices remotely with a cell phone after someone rigged a bomb to get this, a cell phone. Also people live-streaming on Facebook with their terrorist activities onboard.

Lastly, some of the older planes do have interference from some older cellular devices.

Some risks and costs will just be very slow to adopt, at least in the USA. There is too much money fighting any kind of upgrade.

Reply to Scientists have proved goldfish do have good memories and are able to navigate their surroundings. A team from Oxford University trained nine fish to travel 70cm (2.3ft) and back, receiving a food reward at the end. The study disproves the long-held belief goldfish have little or no memory. by Tardigradelegs

It's not long held. It's also been disproven before too as a team of scientists created a sort of vertical maze with clear acrylic walls and after several tries the fish learned how to get around the invisible walls and where they were located. They learned where the walls were, and how to get around them.
