I have to agree with Krazy Ivan - Your teacher is full of it...
The B-2 bomber is the most accurate bomber of all time - able to drop 80 GPS guided munitions in one dump and they ALL hit their targets - this is
unpresidented in the history of war in the air.
Where is the need to make the Shuttle a bomber?
Shuttles & Spaceplanes
The shuttles are for the most part transport trucks and research labs...
Have you considered the possibility of "black ops" operational spaceplanes?
There is some pretty compelling evidence that something is going on in that area.
One interesting note, the Germans in WW2 had an effort underway to build a spaceplane with which to bomb New York.
A German scientist named Saenger developed it, and it was called the "Silver Bird" or "The Amerika Bomber".
Their design was one that was not actually an orbital spaceplane like the shuttles, (I think orbit requires an escape velocity of 17,300 mph) but
rather a design that skipped off layers of the upper atmosphere...
A rocket powered hypersonic vehicle and it was on the drawingboards in 1938.

After the American Operation Paperclip gathered up all the scientific data on German advanced technology research the US came out with plans to build
a space plane in the late 1950's...
It was called the X-20 Dynasoar, with a rocket booster to get it in orbit, it was the first concept for an Orbital Reentry Vehicle, (ORV) that saw
actual development.
The X-20 spaceplane was cancelled by JFK's defense sec, Rbt McNamara in December 1963 right before it was supposed to start in production. (Some
believe that rather than being killed off it went "black".)

Conclusions?
After the Dynasoar there were numerous other spaceplane projects involving different shapes, propulsion methods, etc.
These spaceplane projects went on through the 60's, 70's.. then the Space Shuttles came out ... all the way to present day with the X-33 and Hyper-X
projects.
The fact remains this is old technology that simply continues to be updated with every new spaceplane project, and there have been ample signs that
something very fast and able to fly very high is lurking about out in the deserts of the western US.
Couple that with the age & history of this technology and one begins to see how naive it is to assume that there have been no spaceplanes
surrepticiously developed and operational over the 66 years since Sanger drew up plans for Silverbird.
