There is an easy way and a hard way.
Solutions: one-step solutions: W-wing (69), or a finned x-wing (6); or a variety of multiple-step solutions - color (1), finned x-wing (1), skyscraper (6), etc.

| Yes, Crunched's solution was the one I spotted and leads to a simple solution. I will have a look for the W wing though. |

m-wing {1,6} takes out 6 in r4c5 for another solution.
(6=1)r4c9 - (1)r4c2 = (1-6)r6c1 = (6)r6c56; r4c5 <> 6 |

I think you must mean c36 for the 'scraper.
