Ok, I'm curious now. Why would the MD-8x have opposite deflecting elevators? This is a fly by REAL wires aircraft so I'm surprised that the mechanicals allow this deflection to occur. The picture shows a taxiing aircraft with flaps deployed so all hydraulic systems would be pressurised.... I'd call it if I saw that.
As previously mentioned, I remember seeing a F100 commence the take-off role and I commented to my Capt that he was clean (the F100...) and quick as a flash he said "aircraft rolling, check flap" to which they replied "thanks, we take-off clean".
If you see something as a pax or a crew you MUST highlight it. Period.
