Referring to MACHINE DESIGN March 7, 1991:
Starting on page 56: 

	The author talks about two separate decisions. Selection of 
the YF-22 or the YF-23 and Pratt & Whitney's YF119 or GE's YF120 engine.
"Each team has designed and built two prototypes, one configured with 
Pratt & Whitney engines, the other with GE's." Yet, this group always
discusses the Northrop/GE plane versus the lockeed/PW (I hope I have
that right) face off. Was it two separate decisions or what?
	The article has a great picture of testing the agterburner on the 
F119 engine.
