Very interesting information being tossed around, some points.
.
This accident could have been prevented a few different ways, let's see:
.
1. Some system as
AlexL points out that prevents REV being selected until thrust levers are retarded.
.
2. An auto thrust system similar to the Boeing's that retards thrust automatically at a certain height,
.
3. By Airbus modifying Maintenance procedures on one T/R inop; Simply lock both T/R's out.
.
4. Another idea by
Tyro, whereby T/R deployment is dependent on spoilers being deployed, thereby giving you the go around option.
.
5. The crew following the current MEL operational procedures for T/R inop.

6. The Big Red Button.
