Was this project from 1925 a Bréguet co-operative effort?

The Landes-Bréguet Monoplane Glider has wings similar to those of a gull, and should be very efficient
aerodynamically, but the wing construction was too flexible, and no prolonged flights were made.

The only other glider flights witnessed during our stay
were short hops by the Nessler, and various unsuccessful
attempts to get the Landes-Breguet off the ground. This
machine has a single central skid, and as soon as the helpers
at the wing tips let go the machine heeled over, the wing
touched, and the machine cart-wheeled on the ground.

A glider of most unusual design was the Landes-Breguet,
also shown in one of our photographs. This machine has
arched wings, somewhat like those of a gull, and in model
form a machine of this design has won a number of prizes
in competitions in which the model gliders were launched
from a captive balloon. In the full-size glider, however,
difficulty was experienced with the wings, which were constructed
entirely of bamboo, and were in consequence
extremely flexible ; so much so, that it seems rather doubtful
if the machine would be safe to take up, at any rate in a
gusty wind. The fuselage, which appeared to be so short
that the rudder control could not possibly be effective, was
built up on four duralumin longerons, with three-ply formers,
and stringers of split bamboo.
