Support with Roblox Air

Greetings Robloxians,

I am in the works of modeling a plane. I have it finished and i test drove it. It shouldn’t be more than a Mach 7. I am trying to build a realistic airport and testing this plane lead to a explosion/implosion at altitude 1272.

My questions are the following:

Does roblox have a speed of sound? (Does it coordinate with the real world? (322m/s)

What else could be effecting there is no scripting errors?
