Having just participated in this summers Critical Item List reviews for the 
Space Shuttle Main Propulsion System I took out the Flap Electrical 
schematics and applied the same rational we used this summer.  The Limit 
Switches, Flap Switch, Wiring and Relays (both Contacts and Coil) are all 
single point failures which could lead some not-so-fun consequences (landing 
with Flaps at 8deg reflex / go-around climbout with full flaps).

I plan on installing an override system using 2 pushbutton switches on a 
separate breaker wired to move the flaps up/down if the primary system 
fails.  Normally the breaker will be open (I'll check the system in 
preflight) and only used if needed.  Seems like a small weight/complexity 
penality if you ever really needed it.
