My expierience with flying in CB´s is limitied, as i tried to avoid them as much as possible. Once was in tactical formation low level in northern germany, my flightlead was heading straight for the Cb in front with heavy rain and visible lightning. I told him I would turn around. His "no, i go for the target" was the last thing I heard from him over the radio, because shortly afterwords he got hit by lightning and turned around waggling his wings for help. All radios, radar and most of his nav stuff was gone.
I left the expierience, what hail can do to an aircraft to the test pilots. Following pic is a T-38

I think no sensible FJ-pilot would steer deliberately into a CB in peacetime flying, and when ending up in one would try to get out as fast as possible.
