Oh, no! I butchered the name of our hero engineer. He's Frank Landspurg (not Dave Landsman). After a long carreer at Motorola, he passed away in 2014. His obituary says that he was most proud of his supporting the Apollo missions. We are very proud of him too! If anyone knows any of his surviving relatives, let us know!
