It does seem a high speed for less than 6 minutes after takeoff and at low altitude. Is it even credible?
If you stayed at low level and didn't pull the power WAY back (eg if you didn't know what speed you were doing) you'd very quickly (less than 6 minutes) be going VERY VERY fast.
Done a low-level level-off recently?
