Seems you guys are pretty far off on the actual speed of the viper(falcon) by a lot.
From Wikipedia:
Performance
Maximum speed: 795 kn (915 mph, 1,472 km/h) (Mach 1.2) at sea level
1,147 kn (1,320 mph; 2,124 km/h) (Mach 2.0), clean configuration at altitude
they reference the source material on the website.

I feel this is needed ASAP especially since you are releasing an update that will add more drag to an already underpowered flight model.
