Actually this entire question and solution is about adding
and substracting velocity vectors and a perfect example of Einstein's
relativity theory.

No, this is strictly Galilean relativity (from four centuries ago);
Einstein's relativity has no bearing on this discussion.

I don't agree completely. But your right that Galilean blabla has to do
with this but [...]
So does Einstein! May I remind you of one of Einstein's
many mind experiments... The one about a train moving at a certain
speed, an observer inside the train walking to the front of the train
and an observer outside the train, standing still...

That's a classic thought experiment in support of Galilean relativity. Of
course Einstein was familiar with it, but it's part of a theory much older
than Einstein's.

Sure, it's all connected to eachother. Einstein didn't invent
everything you know, he just used the tools and perfected them.

Einstein invented quite a bit, including special and general relativity. But
those theories of relativity are not involved in the simple vector-addition
problem under discussion.

Whatever. I give up. You win, smartass. This is getting too far off
topic anyway. The question was, will the plane fly yes or no. The
answer is yes. Period. My vectorial explanation was a good start in
trying to explain this.
Happy flying!
