Bengo/Sandy Parts - if a RAS goes wrong you could lose upto 1000 people. I'm not aware of an aircraft crash that has killed that many people.
Hell, losing NOTTINGHAM would've lost upto 45 people in one go if it had happened slightly differently. ENDURANCE was an utter fluke to not be run onto shore during her flooding, and she had about 60 people on-board. Aviation is nothing special I'm afraid.
