Some time ago, while thumbing through the Jet Airliner Production List, I came across a Convair 880 belonging to Delta Airlines, which crashed within a month of delivery, while training at ATL. I wondered if this could be the shortest lived airliner. But it wasn't; there are others, one lasting only a day:
3/3/53 Canadian Pacific Comet 1A; delivered 2/3/53 and crashed in India. CF-FUN
26/6/88 Air France A320-100 at Habsheim. Delivered 23/6/88 (3 days old). F-GFKC
1/10/66 West Coast Airlines DC9-10. Crashed PDX; delivered 16/9/66 (15 days). N9101
23/5/60 Delta CV880. Delivered 6/5/60. Crashed ATL.
11/7/61 United DC8-12. Delivered 16/6/61. Ran off runway at DEN. 25 days.
30/5/61 (NB, barely 2 months before the above). KLM DC8-53, PH-DCL, crashed into sea shortly after t/o from LIS. Delivered 1/5/61 - 29 days old.
In addition, a Braniff 707-227 crashed on a dry riverbed during a pre-delivery test flight.
