The RQ-1 Predator had an accident rate of about 30 per 100,000 hours
earlier this year. [...] Older model UAVs had much higher rates (up to
363 for the RQ-2A). But these high accident rates have come way down
in the last decade. UAVs are expected to follow the experience of
manned warplanes in this area.

For example, the new F-22 an accident rate is about 6 per 100,000
hours. F-15s and F-16s have an accident rate of 3-4 per 100,000 flight
hours. India, using mostly Russian aircraft, has an accident rate of
6-7 per 100,000 hours flown
