Wow, Cartridge starts. I was always impressed when the elephant walk began. Only thing missing was all the black smoke from the G models.  According to the caption on the video, those were "G" models. Video from 2009 = not "G" models. I hoped they checked to make sure none of them had live ACM's uploaded.

If those were "G" models, by the time #2 or #3 went by, all they would be recording is black smoke, and lots of noise.

I think they burn coal. |

Why do B-52's produce so much black smoke? Older model B-52's (A-G models) used water injection to boost thrust on takeoff. When water was sprayed into the motor, lots of black smoke magically appeared. Older KC-135's also used the water injection process. |

And current ones put out a decent amount of smoke because there are eight old generation TF-33 motors that aren't as efficient as newer designs. |

Quoted: According to the caption on the video, those were "G" models. Nope. This is a video response to Boeing B-52G Stratofortress Minimum Interval Take Off (MITO) I remember reading once (with artist's conception) an article about a Boeing proposal to re-engine the B-52 fleet with four PW2000s RB-211s. The Air Force's response was, "Thanks, but no thanks. With the retirement of the C-141Bs, there's enough spare TF-33s to last." |

I used to live at Fairchild AFB during the 70s when Dad was a BUFF pilot in Fs and Gs. The alert forces were armed with Hound-Dog missles. When the base pulled an ORI the planes would launch with a requirement of eight minutes to the first AC off the ground. It was an awesome sight with a KC-135 running water injection followed 30 second later by a B-52 with all eight engines spewing black smoke from the water. The KCs took off first and the BUFFs would take off with less than full fuel to top off when they caught the KC.
You should check out "A Gathering of Eagles" with Rock Hudson for a pretty accurate look at a SAC base during an Alert. Keith |

The later turbofan versions smoked less(today would be considered alot),as they didn't need use of water injection. Water injection was a PITA,as it used distilled water,plus it weighted alot. |

"G" models were turbojet,"H" models are turbofan,as you can see the fan's outlet on the nacelle. Older engine DC-8s(JT-3D) would also smoke like this,along with the loud crackling sound. Sucked to be on the ramp and downwind of one too.
