Ari, first of all, *epic* congrats on getting HP over "The Threshold of Exceedingly Few"!!
I'm guessing that video above is of the I140, right? I have six of these, and flown one, but it CATO'ed. Destroyed the 4" Bomarc's pod, but thankfully, the glider managed to burn off the excessive airspeed and glide back in, albeit too close to the cars.
I've only flown one J90, back in the '95ish time frame, and that was cool. Did use a J180 as my first shot over an I back in the day, but after a perfect boost, Excelsior did not transition well and 'Tomcatted' in, damaging the front tubing some.
Sorry to hear of Have Pink's ultimate fate though, been there. Just like Vulcan's legacy, HP 'did its job', so to speak, to which you walk a little prouder.
Congratulations again, Ari. BTW, did you have to control the boost any on the J90's ascent? I'm guessing probably, since getting something like this to boost hands-off for a 9 sec burn is not good on the nervous system. Can't wait to see the video of this!
