I have no intuition for this, as it is not modeled in KSP :) I’m trying to imagine a collision cascade that would generate debris with a significantly higher apoapsis than the original satellites… perhaps a head-on collision between prograde and retrograde orbits that ends up “squirting” some debris at extreme velocity in the normal/antinormal direction? Alternately, an object on a highly elliptical orbit (probably already space junk) near its periapsis with max kinetic energy hitting a satellite prograde?
