September 9: The incident was fixed during the morning, but the team encountered another major problem: the wind. Demonstrator 2B was designed to be launched with a wind speed of about 14 km/h, but on September 9 the digital weather station indicated an wind of about 50-60 km/h with turbulences. The launch in those conditions was impossible because the calculated safety zone was way out. The technical team recalculated the launch configuration and the fuel quantity was drastically reduced to 19.6% from the maximum capacity. In those conditions the safety zone was respected. Further more the reduced fuel quantity allowed us to obtain a higher speed and acceleration during on the launch pad, an important thing in those wind conditions. The modifications were communicated to the Command Center and the team requested the take-off approval for.
With aprox. 7 sec before the take-off command, the pressure pipe smashed an electrical wire that was connected to the engine electro valve. The cable was pulled out from it’s position and the engine was out of electricity. Because of that, the engine was fueled and the vehicle was launched.
The event was broadcasted live on many TV stations.

September 10: The ARCA Team members arrived to the Command Center to read the flight data. The preliminary data indicated that the launch data are: 1000m altitude, 630 km/h, 2100 m range. In those extremely conditions the recalculated trajectory with only 10 min before the launch was a major success. The Command Center specialists congratulated us because the vehicle landed exactly at the safety zone limit.
ARCA team members wishes to thanks to the sponsors, to the Defence Department, the Air Force, the Launch Site representatives and the Flight Research Center.
After this event, ARCA team members will take a one week vacation and after that we will continue with the ORIZONT construction which will be presented to the mass-media and public in short time.
