A while back Saber and I tried to land an F4U on top of a B24 in flight (piggy-back).
Being "oh-so-careful" and matching our airspeeds as closely as possible (which would appear to minimize lag effects- since they're a factor of time, greater speed differential should increase the distance between the perceived location of the other plane and his "actual" location) we found that it was impossible.
The plane in back (F4U) always got a collision and died. The B24 never did. From the F4U, it would appear that your gear was centered over the B24's wing (we were hoping to get a prop-strike, and drop the F4U gear over the leading edge of the B24's wing, leaving us "stuck" piggy-back). As soon as any contact was made from the F4U's perspective bad things happened.
From the B24's view, the F4U would break up and fall when the F4U was still a bit behind the horizontal stabilizer of the bomber. No contact between the two was ever apparant from the B24's view, so the B24 never took any damage.
This just supports the previously stated cause / effect of how the ram model works. It also shows that it is "fair" from both perspectives.
