Aviation
The CT-114 Tutor entered service in 1963 and is being retired. The Snowbirds have flown it for the whole of their existence, and their last seasons with the aircraft are the last time this particular thing will be seen doing this particular job.
The airshow pictures are the obvious part. The ones I am more interested in are made on either side of the display — ground crew, taxiways, the apron once everyone has gone — where the machinery is at rest and its age is visible.
