regarding the detroit crash, please remember that detroit is lower than madrid in elevation
that the detroit crash happened at night...and it is harder to fly at night as it is a semi instrument condition.
detroit was also cooler at the time of the crash than madrid was.
AND FROM THIS CRASH (detroit) ON, we learned: firewall power, flaps 15 if you stalled after takeoff...but somewhere that seems to have been lost.
we also learned a trick called "muscle memory"...that we couldn't takeoff without wiggiling the flap handle and making sure it was set in the detent.
long ago I suggested to my airline that we set flaps prior to leaving the gate area and have a visual confirmation by the mechanic in charge of pushback.
that didn't make sense to the boss
ha!
