Lockheed L-1011-500 TriStar. Operated for Air Lanka, British Airways and Air Transat. Scrapped.

Vuelopedia is a work in progress: it currently holds about 30% of the information we expect to have by the third quarter of 2027. Although we use only official, highly reliable sources, some aircraft data and history may still contain errors or inaccuracies. We work hard to clear every anomaly from the records using specialized verification tools.

Memories coming soon

The register of memories is not open on this aircraft yet. We are enabling it gradually, record by record, as we consolidate each aircraft's information.

Before opening it we check the aircraft identity — its registration, its serial number and its model — against the civil register of the authority that registered it, so that every memory belongs to the exact aircraft that lived it. When that work reaches this record, the register will open here.
