S'il suffit pour résoudre un problème de le discuter bruyamment, quelques-uns des promoteurs de la navigation aérienne sont dans la bonne voie: ils sollicitent l'attention publique par tous les moyens possibles, ils lancent des ballons d'essai dans la presse et dans l'atmosphère, ils n'ont point de cesse qu'ils n'aient fait parler d'eux. Ils feront bien cependant de se défier du public français: on le séduit facilement par des promesses éclatantes, il ne lui déplaît pas qu'on fasse, pour piquer sa curiosité, quelques frais de mise en scène; mais il y a dans cette voie je ne sais quelle limité délicate qu'il ne faut pas franchir sous peine de cruels mécomptes; il y a je ne sais quel rapport à garder entre les espérances qu'on excite et l'effet qui les suit. Nos lecteurs savent comment MM. de Ponton d'Amécourt, de La Landelle et Nadar ont repris de nos jours la question anciennement agitée de la navigation aérienne. Ils déclarent qu'il faut renoncer à diriger les aérostats, c'est-à -dire les appareils gonflés d'un gaz moins dense que l'air, et qui s'élèvent dans l'atmosphère ! en vertu de leur légèreté relative. Ces appareils en effet offrent toujours une très grande surface, et en raison de cette circonstance la force motrice dont ils peuvent disposer ne leur permet pas de lutter contre l'action du vent. Que faire dès lors ? Imiter les oiseaux, qui volent en étant beaucoup plus lourds que l'air...
