One can infer that very little was done based on the F-18 pilots being on a routine training mission.
I don't see the natural inference of "little being done" from a routine training mission by 2 aircraft.
We have had no report from the Princeton as to what else they might have done or to whom this might have been reported.
There likely was nothing new that any additional personnel could tease out of such a common situation.
There were standing orders for how to handle yourself in such situations. The orders to try and shoot them down had been rescinded quickly after the craft started blowing airliners out of the air in response to the military shooting at them every time they saw them. Wiser heads in D.C. quickly decided that was not a good standing order to leave in force.
Such situations had become routine enough to not likely be able to obtain much new intel in such situations. But they were exciting to the military personnel involved, nevertheless.
