The 707 roll was indeed a barrel roll. Check it out on Jay's webpage.

Again....check the definition of a "barrel roll" at the web site posted
by Peter and my previous post. Big John, dispite his thousands of hours,
simply doesn't know what a "barrel roll" is. I'll put my Navy training and
22,000 hours and ATP/CFI ratings up against his anyday. :-) I've been
waiting for two years for John to post an authoritative source for his
concept of a "barrel roll".
