I'd give them the link to the NTSB db and

N T S B - Aviation Accidents - Index of Months

have them look for incidents/accidents:
1. In the type of plane they are training in
2. In and around the area the are flying
3. The actual "N" number they're flying (3 planes I've flown are there, fortunately I was not)
4. Have them realize the # reportable per day/month etc.

VFR into IMC and Fuel Starvation/Exhaustion are prevalent - even for non-students.

The query link (for a/c type, or location, etc) is : NTSB Aviation Database Query Page
