Comment: Added graph of inflation time vs. airstream velocity

altitudes = linspace(90000,150000); %range of altitudes in meters
machs = linspace(0.5,2); %range of Mach numbers
altitudes = convlength(altitudes, 'ft', 'm'); %convert altitudes to meters
[T, a, P, rho] = atmoscoesa(altitudes); %use Standard Atmospheric Model
velocities = machs.*a; %calculates all possible deployment velocities

Then, we can generate the following graph of inflation times based on velocity:
