If your car breaks down a couple of miles from home and you call a friend and tell him you're stranded, are you lying? What if it's 20 miles away? But uber exists? What if uber is extremely expensive right now at $2000? But there's a guy next to you offering to sell you a bicycle?
In the end, to ask the question "were they stranded?" we have to unpack "stranded" and figure out what is the question we actually want answered. Is it about the feelings of the astronauts? Their preferences? The danger level they're in? Is it about Boeing's culpability? Is it about whether we can safely call Trump a liar? Musk?
