There’s no way this is true. Why not use more bolts it makes no sense.

And my head is only held onto my body by one neck.

I'm fairly sure the engine will stay on with both bolts removed. I suspect they are retaining bolts and take very little strain

That's nonsense. Here's the forward engine mount for a B737NG http://www.atirepairstation.com/737-ng-forward-engine-mount-assembly-4/ http://www.atirepairstation.com/737-ng-forward-engine-mount-... And here's the aft mount https://www.atirepairstation.com/737-ng-aft-engine-mount-assembly-3/ https://www.atirepairstation.com/737-ng-aft-engine-mount-ass... And here's a well-written post about this very same myth as it relates to the 737NG, describing exactly how it's all put together. https://aviation.stackexchange.com/questions/23151/how-are-engines-mounted-onto-wings https://aviation.stackexchange.com/questions/23151/how-are-e...

We're about to see so much propaganda pulling government line items out of context so you can get mad about it and support a political movement to defund everything of value in the state.

The under development 777X has a slowdown in its testing due to some issue with its thrust link (part of what the engine to plane connection is called): https://www.flyingmag.com/aircraft/boeing-responds-after-suspending-777x-test-flights/ https://www.flyingmag.com/aircraft/boeing-responds-after-sus... The actual mounting of the engine is more complicated than the linked tweet implies though.
