This was my first launch ever that I have seen live in person and it was absolutely amazing. Congratulations ULA and thank you for this unforgettable experience.

I love how at 1:12 you can see the core booster has a shorter flame length than the side boosters

Gee, the Delta IV has three RS68, more thrust than the four Antique Historical Reusable Space Shuttle SSMEs used on NASA's SLS. NASA should switch to RS68A instead of the Priceless SSMEs.
