Launch News Delta IV Heavy with NROL-44

[GLS]

Another big spy satellite going up.... but not just yet...

As usual, the PAOs look like fools when something happens that isn't in their script. ?‍

That was the most spectacular launch abort I've ever seen IMHO

There appears to be lot of fire involved in every launch with that launcher particularly. Makes me hold my breath every time. I don't recall seeing launch aborts after engine ignition before. At least we avoided a big fireball that happen to Antares sometime ago.

The fire is entirely normal and expected as the RS-68 starts very hydrogen-rich so it belches a cloud of H2 right at engine ignition that rises and sometimes gets ignited. The very first Delta IV Heavy burnt all three LH2 tanks prior to lift-off and suffered no ill effects. Here's a set of photos that shows just how crispy the LH2 tanks got: https://spaceflightnow.com/delta/d310/041221launch/01.html and https://spaceflightnow.com/delta/d310/041221launch/02.html
