Probably first worth making doubly sure the BEA have not released an English version that you've missed ?
Mixture. Thank you very much for your quick reply. The problem is that the accident in question was a French Navy maritime Lancaster that made a hash out of landing in wet weather at Wallis Island in the South Pacific around 1963. There were later shenanigans between the French authorities and a lone Australian whose hobby was finding and restoration of crashed wartime aircraft in the South Pacific area. The Aussie was diddled out of the Lancaster by the French at the last minute before he was due at Wallis Is to start work on it to get it to Australia.
Although he failed to get his hands on the Lancaster at least it forced the hands of a French aviation museum at le Bourget and they had it shipped to France. 30 years later it is now partially restored to static condition at Les Ailes Ancienne museum at Saint-Mande in France.
I have around 10 pages of correspondence in French on the project. Hence the head-scratching on the translation.
Thanks again,.
