I read somewhere on the net last week about a collision between two light singles. each carrying a flight instructor and a student. One pair survived and one pair was killed. It was said that one of the students was being given IFR instruction. I forget why the other one was up. Isn't the situation of the pilot being under a hood about the most hazardous planned one that exists? Is the Instructor's view considerably reduced when his student is under a hood? The particular accident account did not say anything about a hood, and I don't know if it was the IFR pair who survived.
