Any read the book L'envol des Alouette?

Hello all,

Trying to dig-out some development history of the Alouette family of helicopters and I came across a reference to “L’envol des Alouette” by Charles Marchetti.

That piqued my interest, as a gentleman of that name was the Chief Designer at SNCASE / Sud responsible for the Alo.

Unfortunately no copies seem to be easily available anywhere ( ISBN 2283751136 ) so was wondering if anyone had read it and could comment on whether it was worth hunting-down.

Thanks!
