I don't know whether the following are two stories or the same story told two different ways. However as they are reported separately, I'll assume that they are two separate stories.
Whilst Dunkerque was under German occupation Charles Leteneur occupied his time clandestinely building a glider. Now one might say that this is not the wisest choice of pasttime for a French citizen living under German rule, but no doubt M. Leteneur had his reasons. It seems that he completed the glider but, not surprisingly, there was little opportunity for him to use it in Northern France in 1944. When the time came for the civilian population to be evacuated to Lille - presumably in consequence of the Siege of Dunkerque (September 1944 - May 1945) - he had to leave his glider behind him. His family and friends wanted him to destroy the glider before he left but M Leteneur would have none of it. So the glider remained, chez lui, hanging from the ceiling of his workshop beneath his house. The glider subsequently was discovered by a member of the German garrison, who thought he'd happened upon a 'den of spies' and so reported it to an officer. The officer accompanied the soldier to the house, the soldier believing that he'd be instructed to destroy it. But he wasn't. Apparently the officer had, in pre-war years, also been a glider builder and he instructed the soldier to leave M. Leteneur's glider untouched - with the injunction that he'd break the head of anyone who touched it. The soldier did so and the officer's injunction was heeded. Thus when, some months later, Dunkerque was liberated and M. Leteneur was allowed to return to his house, he found his glider in the workshop just as he'd left it.
Sadly, I've been able to find nothing which identifies the glider or its fate but, having regard to the enterprise to which M. Leteneur next turned his hand (or maybe that to which he was turning his hand contemporaneously?), I like to think that the glider which the German officer saved was not only built but also designed by M. Leteneur and that it saw some service with the Club Aéronautique de Dunkerque in the post-war years. So if anyone can shed any light on this ..... ?
Now to M. Leteneur's powered aeroplane. The text that accompanies the photographs which I posted claims that M. Leteneur started work on his Train powered monoplane - presumably in his home workshop - whilst Dunkerque was still subject to bombardment and that he completed it amongst the ruins of the bombed city. By August 1947 it was undergoing flight trials. I don't know whether these were successful or what became of the aeroplane. I've found no subsequent mention of it in the French aviation press or elsewhere. But I can't help but think that the tale of the reprieved glider may actually relate to this powered aeroplane - certainly if it was being constructed in M. Leteneur's home workshop. Like 'Chinese Whispers', the first story related may have started rather differently to how it finished - and the German officer may have been an amateur light aeroplane builder who couldn't bear to see such aeronautical endeavours being destroyed. If so, then it's him I have to thank for supplying me with the means to offer an obscure mystery aeroplane that provided our assembled experts with a decent challenge!
Anyhow, enough of this. Let's have the next one, please, Walter!
