Someone actually tested this using state of art flight simulator - found
that 767 could easily reach 650 mph (.86 mach) at low altitudes
767 has reputation as a "hot ship" do to high thrust engines and a
clean exterior configuration (no external drag inducing bulges)
In fact 767 is certified for one engine take off at full load and can fly
the Atlantic on only one engine.
Here is long article about the test
In fact AA11 was calculated traveling at ~470 mph when impacted North
United 175 was estimated at some 530 to 560 mph at impact time
So answer is yes 767 can exceed 500mph at low level.....
