The objects speed can be modified by a Nasal script. YASims winch/aerotow/anchor can be connected directly to any AI object and (with some Nasal code, which copies the location) to anything else. The force on the other object is calculated and stored in the property tree. Some Nasal code only need to take this force, multiply it by dt and divide it by the objects mass and add the result to the objects speed (which need to be converted to (and afterwards back from) the earth-coordinate system). If we use a AIBallistic object, the gravity and drag effects would be calculated automatically. Therefore external cargo missions, SAR missions or even banner-towing with realistic forces on the aircraft should be possible with fg1.0.0
