cecil...you make a great point...funny, if I had a full plane and it was hot in spain, I would start both engines just to keep the plane cool (air conditioning)

if all human beings did everything correctly, we would have very few airplane crashes. I can't tell you what the mechanic did...he may have done everything perfectly...but with the only thing involved in mx items prior to take off being the rat probe, I had to come up with a failure path.
it has taken a few days to finally decide that the item in question was the RAT probe...before, some were calling it "an air intake valve"...which I have not heard of
as to the "other" things that might show up...I will stop for now and wait for the report
I've given one possible scenario involving the RAT probe which could possibly lead to a takeoff without flaps/slats extended.
it is just a scenario and may prove wrong
I DO ASK all my fellow pilots to always check the "killer" items just prior to takeoff...and that includes flaps/slats and trim
among other things
