The short messages from aircraft (via ACARS) are all unencrypted.
That's right, they're sent in plane text.
Hi, I'm Tess
I'm a 33yr old poor, disabled, autistic, white trans woman living in the UK.
I mainly post puns and silly things. And occasionally: grumbles, quiet musing and physics.
I'm learning to program and hoping to make a game.
I'm also a carer for my wife @FrazzledBrynn
