J'ai pu effectuer ma simulation en me basant quasiment uniquement sur l'entrée de son blog qui détaille son observation, remarquable par son niveau de détail.

La simulation doit être considérée comme un travail en cours dans la mesure ou quelques questions mineures en suspens pourraient modifier légèrement la simulation. Mais il reste que c'est aujourd'hui la meilleure simulation existante d'après Tim lui même.

Voici pour référence les informations complémentaires qui accompagnent la vidéo :

Ley Family Observation v1.0 (Phoenix Lights) fr translation

Blending effect with the color of the sky.
Thickness set to 1 meter. Might be even less since witnesses couldn't see any thickness.
Transparency : no transparency.

Omega shape shifts to V.
Environment map from Ley's home.
Takes into account absorption of specs of light on the surface of the convex meniscus.
Simulates smear/distortion effects between the arms of the V.
Does represent the bulge on the top, that was seen when the object was leaving.

Time Stamped. Time = 0 when the tip of the V is at the closest.
Altitude 75m
Wingspan 460m (1500f)
The size might be overestimated. Maybe by a factor of 2. However the ratio between the real and estimated angular size is close to 1 !

The streaming particles effect inside the light is much too exaggerated and very probably does not represent what was seen. 
Doesn't simulate mirage effects (duct), under and over.

As long as the witnesses do not state what's wrong, in the simulation, I cannot correct for that.

Je ne saurais que répéter la minutie de la description de Tim et la précision de son observation. Exemple : il indique que la trajectoire du V l'amenait selon une ligne qui fait 20° avec sa route. C'est exactement ce que je trouve à 1 pixel près avec google earth quand je place le V sur la trajectoire qui passe par les coins caractéristiques. En effet, la ligne de vol qui fait passer le coté droit du V exactement au dessus de la tête de Ley et qui fait passer le V pile dans le trou de Hatcher Path …va de 340° nord vers 160° sud, et pour finir la rue ou habite Ley est orientée exactement nord/sud autant que je puisse voir dans google earth.
J'avais fait la simulation avant d'avoir cette info de ley, et elle place le V selon un angle qui le fait venir de 19.23°, à gauche du point cardinal Nord. One est donc globalement précis à 0.7° !
Pour info, la tête de la comete Hale Bopp était à environ 35° à gauche du point cardinal du nord (azimut 325°). Mais la queue de la comète était très étendue et partait sur la droite…

Ce qui me chagrine dans la simulation après avoir énormément ajusté les paramètres pour prendre en compte tout ce que dit Tim :

Tim Ley : “Very good simulation - you have captured the essence of the event. Most importantly you were very accurate in the abstract quality of the object - the fact that it was sharp-edged darkness with 5 light-holes set into it. The National Geographic special that was on cable last February was only accurate in determining the size of the object (1,500 feet) because in their rendition they inacurately pictured the object with a metal surface and thickness to make it look like the thing which I saw pass over my house was the actual craft. I believe what I saw was the “foot” of the craft that extruded outside of a force-field that hid a huge craft within. I have attached a YouTube video of a 2007 TV spot about my drawing of the craft in which they animated it. http://www.youtube.com/watch?v=gr0cdjT3gsQ Until your simulation this little animation was more accurate that the National Geographic show's version.
