I'm with Chuck on 700X. As far as what engineers can and can't do, a Bloomberg writer visited last week. Her father was a field worker in bare feet, his school a slate hanging from a tree, saw a discarded application for college in Bangalore, filled it out to become civil engineer and graduated with doctorate from Southampton University in England, specializing fluid dynamics, went on to assist in design of dams, bridges, jet fighters and helicopters. I can't imagine recoil physics as beyond any engineer.
King;
When the boat left I believe you were still standing on the Dock. First the subject was 800X not 700X. Recoil physics was obviously "Beyond" Gough Thomas AKA Garwoood else he would not have made the Utterly Foolish statements about them he did, doesn't matter what Sheepskin he had.
