Is it possible for the pilot to feel passing through the sound barrier in an F-16?
What about other modern aircraft, will you feel anything? Do you need to go back to really dated designs before you can notice this, is it a problem of the past, or did the documentaries I watched which discussed this problem grossly exaggerate it?

In an aircraft designed to go supersonic, it's an absolute non-event, and one is only aware of it by observing the instruments, and noting diminished control authority-- slower roll rate, etc. At least, that was my experience in the T-38, and according to every account I've read.
If the aircraft is NOT designed to go supersonic, then the experience can be quite different, although that mostly comes from loss of control at high Mach numbers (starting in the 0.9X range, as best I recall), rather than anything that occurs right at Mach 1.00.

I've heard of the P-38s going transonic in dives and not being able to recover until they can get into denser air.

Generally, the T-38 had an amazing roll rate, like over 360 degrees per second. Supersonic, though, it was way less, maybe a quarter or an eighth of that. Don't remember exactly when it dropped off; it was NOT a noticeable thing at Mach 1; you noticed a twitch in the airspeed & altitude indications, but only that. Then you try the aileron roll, and it seems to take forever. We didn't demo that at .90, .95, etc for comparison, unfortunately.

@BillDOe: There is no recorded case of the P-38 going faster than sound. There were problems in high speed dives that cause loss of control, but they were not caused by the P-38 breaking the sound barrier. There were P-38s that broke up in dives. The "bang" from the breakup was (falsely) interpreted as a sonic boom.

@JRE He said transonic, not supersonic. The loss of control authority on P-38s in high speed dives was related to parts of the airflow around it becoming supersonic (but I agree definitely not the plane as a whole), see en.wikipedia.org/wiki/Mach_tuck
