So this poor traveller at least had sufficient mobility left to be able to drag himself out of the airplane, undignified as that is. What would have happened if he didn't? Don't they have procedures for e.g. unresponsive patients?
And trying to blame a subcontractor doesn't cut it. The passenger was an Air Canada customer and Air Canada should have resolved the issue one way or another without forcing a disabled man to drag himself out of an airplane like an extra in The Walking Dead.
We need any help we can get to net zero carbon emissions, and lab-grown meat is one of the many things that moves the needle in the right direction. Not everybody is going to ride a bicycle and switch to a vegan diet, so the more low-carbon alternatives we make available, the better.
