A GoPro photo can provide many details.
MigFlug is a company that offers fighter jet flying experiences in wide variety of aircraft in Russia, Europe and North America, during a Edge of Space mission with their MiG-29 Fulcrum.
This interesting photo taken by MigFlug videographer Artur Sarkisyan shows the upper end of the Edge of Space flight profile (click below to enlarge).
Here’s the meaning of the points on the image:
- acceleration from a height of 12,000m at a speed of Mach 1.8 (at sea level 2,222km/h or 1,380 mph – at this altitude 1,950 km/h or 1,210 mph)
- Set of the height
- height = 18,000 m
- reduction of height, return from the stratosphere
