The BAC One-Eleven Series 500 is the definitive stretched variant of the rear-engined twin-jet, seating up to 119 passengers versus the baseline 79 of the Series 200, achieved by plugging 4.1 m into the fuselage fore and aft of the wing.

Spot it by:

Longer than the stumpy Series 200/400 — the stretched fuselage gives it a noticeably more proportionate look. The leading-edge root extensions are a subtler tell; at a glance, count fuselage window bays to judge length against any parked 737.

History

British Caledonian and British European Airways demanded greater capacity, prompting BAC to stretch the fuselage and add leading-edge camber to the wing to compensate for the heavier aircraft. The Series 500 first flew in June 1967 and entered service in 1968. Romania also produced the type under licence as the ROMBAC 1-11.

Variants

The stretched 500 superseded the intermediate 400 and 475 in production; the 475 was a hybrid with the 200-series short fuselage but the 500-series wing and engines for hot-and-high operations.

Where you'll see it

British Caledonian flew the Series 500 extensively, as did British Airways after the 1972 merger. UK independent carriers including Dan-Air, Court Line and later British Midland kept the type in service through the 1980s; Loganair operated examples into the 1990s.
