SoS, you wouldn't happen to mean the JAL422 28 Jan 04?. Flt was delayed due to wx at LHR until lunchtime 29/04 when it operated outbound as the JAL422D.
That's the one. Eventually left LHR at about 14.10. on the 29th.
Lots of f**k ups at LHR that night but looks like Japan were trying to avoid the costs of overnight transport and accomodation and got caught out when the flight was eventually cancelled. Flight and cabin crew departed, leaving a handful of ground staff to pick up the pieces.
Correspondence with JAL suggests rather large compensation payouts. On the subject of press interest, apparently one of the passengers did a phone interview with BBC Radio but it was never broadcast, as the Hutton report was dominating the news that night.
