It would be a fun ride when they light the rocket. The telemetry was cool. I know some SR71/U2 pilots skirted the edge of space. I don't know, if they crossed over the boundary or not?

The SR-71A holds the record for highest sustained air-breathing flight of just over 85,000 feet. Even in the US, where the boundary is considered 50 miles high, that is 50 x 5280 = 264,000 feet. I have vague memories of stories of pilots using momentum to temporarily get them higher than 85,000 feet, but I doubt they got above 264K.
