So what was it that melted in Big Lake Park that night? Could it have been a meteor? No, the debris would have been rock, not metal. Piece of an aircraft? It would not have fallen in a semi-molten state. Satellite? Those are made with light weight metals having high alloy content, not heavy manufacturing metal. Space junk? Something falling all the from outer space should have made a significant crater upon impact and wouldn’t have been molten.
