This would be an interesting CVR to hear
I used to fly on BMI DC-9 a few times. I knew nothing of the a/c, but I knew about the wings of a Boeing. One day we flew out and here were the LED's, drooping. On the return I was horrified to not see any drooping LED's. I only paid attention as we turned on the runway, obviously. Too late to alert the CA's, just blind faith that the guys knew what they were doing. Later found out a little about the DC-9 family and the lack of LED's on early smaller models. There was a heart in mouth moment as we hurtled down the thankfully long runway.
in 1983 we bought 2 ex EAAC DC9-32's which had high lift LE devices on the wings - full width
