1. Launch a small lander to a mission.
2. Wait until the heatshield ia detached, but the lander is still inside the backplate!
3. Now disconnect from vehicle. How seems not to matter.
4. Launch an other mission in different crater.
5. Return to the previous launched small lander.
6. Backplate should still be attached and retro rockets are firing until lander goes to emergency mode and touchdown.
