pero puse a 20 y 25 y no los veo. Pero me conformo así. Algo se ha mejorado.

According to this chart, the threshold range for an F-16 (wingspan 9.8 meters) is about 5 kilometers at an average level of contrast of 0.50, and reaches 7km at high contrast rate 1.0. A C17 (wingspan 51.7m), should be visible at 20km and 30km at the respective contrasts. Making an extrapolation, a WW2 fighter such as the P51 with 11m wingspan should be visible at slightly higher ranges than the F16, whereas a B17 (wingspan 32m) should be visible at approximately 15-20 kilometers.
