With no "yolk," does that make the Bus an "egg-beater?"
Ever since Tex Johnston rolled the 707 prototype, a Boeing big-wig (President or CEO, not sure which) has supposedly told the test pilots before the first flight of any new aircraft:
"Don't roll it."
I saw a Youtube clip where the test pilot of the 777 told him "But it can't!"
He said "Just don't roll it."
