This would be a Grumman HU-16b Albatross. Of the 19 and 59 vintage. Almost as old as our facility and still running strong. I was outside in the shop and heard the unmistakable rumbling of the radials running up. Had to run to catch it as it was taking the active for take off. Slow, loud lumbering and still pretty cool to see flying.
