In 6969, Danny's spaceship travels out of the Milky Way galaxy in seconds.
Distance to the near edge of the Milky Way is 25,000 lightyears, or 9.461e+15 meters
Using a frame by frame, they do this in ~26.58 seconds
9.461e+15 / 26.58 = 3.5594432e+14 m/s, 1,187,302 c, MFTL+
This scales to Brian, seeing as this speed is directly stated as being Brian's speed, which in turn scales to Danny
