The submitter used the HTML doc title, which is usually fine, but sure, we've changed the article title.
Thanks! And thank you for deleting this as well. There was no need for my comment to stay open to discussion once it was addressed. No need to give us all more space to go down a rabbit hole.
Can someone fix the title please? It uses X-Plane in the singular 'X-Plane construction begins' rather than the title from the article which is more clear about this being the newest among many explains over the years.
Maybe something like "NASA begins construction of new Super Sonic test plane"
