I believe this story.
Years ago a mate needed to off load a problem.
Had taken off from a rough runway in bad weather with a new FO (Boeing)
With the distraction of the rough runway combined with a deviation from the SID for weather avoidance, the FO never said positive climb, que the captain didn't say gear up.
The knew they had a problem.
Aviate Navigate Communicate.
So they continued to climb and avoid weather, the aircraft didn't climb well and vibrated but as he said it wasn't a gear problem because they had three greens, so it must have been engine problems or weather, 15000ft again looked at the gear, three greens, said he really wanted to hang his hat on a problem and not create a new one and three greens looked good, over loaded by the weather the vibration and flying single pilot.
Raised the gear
