I open up again this old thread only to report that today was launched the second USV, the FTB-2 christened "Polluce" ("Pollux").
The mission started today at 8.45 (CET) from the airstrip of Tortolì-Arbatax (Sardinia) with a stratospheric balloon, at 10.25 ad at height of 24 Km the FTB-2 was dropped from the balloon and started the forseen supersonic maneouvers profile.
Both parachutes (pilot and main) was released flawlessly and the vehicle performed a soft splashdown at 10.35.
At 12.00 the vehicle was successfully recovered by a ship of Italian Navy.
