Questions:

1. How high did it go?

2. How fast was it going when it exited the launcher?

3. How much did the launched object ("lawn dart") weigh?

Q1 is most interesting. Q2 is right behind Q1.

I do suborbital launches every day. Paper in to the bin, me in to bed...

I love the idea of the project, but some numbers would be nice indeed.

Per Scott Manley[1] release velocity was Mach 1, they're targeting Mach ~7 for the final version.
