Question About The 737-300 Series
i was on a KLM 737-300 flight from Schipol Amsterdam to Aberdeen today, and i was sitting in row 18f behind the wing and engines. I noticed once we took off and much turbulence a flap opened on the first pod on the wing behind the engine..... inside it looked like a cap was there... was it an inspection flap?? should it have been open??? it was above a slightly risen bit on the wing transparent looking?? was it the fuel pump access flap?? was it right to be open????
