Depends... What time did the FAA realize that Flights 77 and 93 were hijacked? I would say that would be a determining factor.

Checked lots of press stories and timelines - found nothing definitive on these two flights. However, when the FAA realized these flights were hijacked isn't really the determining factor since highjacking is not a necessary condition for an intercept.
Interception is indicated when a plane a) loses communications and/or b) goes off the flight path it's required to file before take-off, because it keeps a plane in trouble--for whatever reason--from straying into the flight paths of other aircraft.
AA #77 lost radio contact at 8:50 and lost the transponder at 8:56. Shortly thereafter it left the flight path. UA #93 lost communications at approx. 9:20 and there were two quick radio transmissions from the hijackers at 9:22, so sometime soon after 9:22 the plane left the flight path.
AA #77 hit the Pentagon at 9:45, about 49 min. after losing communications. UA #93 crashed at 10:10, about 50 min. after losing communications.
