approach to landed target

set target to "don't land here".
lock relvel to ship:velocity:surface - target:velocity:surface.
lock tarSpeed tomin(200, target:distance / 40).
set taralt to 1000.
lock tarVel to (target:position+up:vector*taralt):normalized * tarSpeed.
lock steering to choose up:vector if alt:Radar < taralt else tarVel - relvel.
lock throttle to choose (steering:mag / (ship:availablethrust/ship:mass))/2 if steering:mag > 0.01 and vang(steering,ship:facing:vector) < 2.5 and ship:availablethrust > 0 else choose taralt-alt:radar if alt:radar < taralt else 0.
on ship:maxthrustat(0) {stage. return stage:number > 0.}
