Rey (with TFA title and Kanan as crew)performs a 3 bank maneuver and lands on a debris field. What happens?

We played it out as:

the manuver is completed and received 2 stress in which Kanan was able to clear one.

When you land on a debris cloud, the stress from that will be assigned before the manoeuvre is completed (Step 2, sub-steps a, b & c. The stress occurs between sub-step b and c). You can trigger Kanan to get rid of the debris cloud stress token, then trigger the MF title, spin the ship and gain 1 stress token. Then after the Perform Action step, roll for possible damage from the debris cloud.

End result: 1 stress token gained from debris, removed by Kanan, then 1 stress token gained from MF title.
