Mexico City, March 17.
The "flying saucers" are really flying apparatuses, probably remote-controlled and capable of vertiginous horizontal and ascensional speed: such are the assertions of four pilots and inspectors of the Mexican civil aeronautics who managed yesterday, for the first time, to chase and approach one of these machines at the time when it was seen around Mexico City.
The pilots stood ready to take-off yesterday at the airfield of the Mexican capital. Their equipment comprised cameras and telephotography devices. One of strange "objects" was reported at the fall of night in the sky of Mexico City: they flew away in pursuit.
The pilots stated that they had been able to note, whereas they were themselves at 6 500 meters of altitude approximately, the presence of a "saucer" which, they estimate, sailed at 10 000 meters approximately of altitude. The machine, according to them, has a diameter of some thirty meters. It is manufactured of opaque material and "has in its lower part a sort of exhaust pipe from which sparks and the flames are emitted."
The same pilots add that when the "saucer" had recorded the approach of their plane the machine started to turn slowly in concentric circles "as if it wanted to let himself be followed", then suddenly accelerated its pace of rotation while launching flames and sparks, and finally started suddenly at a vertiginous speed and was quickly lost in the clouds.
The pilots, who are professionals accustomed with the aerial observations and whose seriousness does not seem doubtful, declared on their return that they did not think that the "saucers" were piloted directly by human beings, since no body would resist such speeds of acceleration. On the other hand, they say that they are quite certain that the machines "are actuated from some terrestrial place by people perfectly aware of the various phenomena of air transport, and in particular of the methods and means available to Mexican aviation."
