Many years ago, I flew as a Electronic Warfare Officer crew member aboard the B-52E on the first exploration of the B-52 in a low-level mission role as well as many hours on "Chrome Dome" nuclear airborne alert - at the time, it was the most massive airframe to leave the ground - now seems like a light weight {:>). So heavy, that on high density altitude days (and there were many in Western Oklahoma), water injection to the engines were essential to get a heavily loaded B-52 airborne. An impressive sight in those days to see this 8 engine monster hurling down the runway with black "smoke" belching from the engines, the engine roaring and heat mirage distorting the view from behind from those engines. Hard to believe how long that airframe has been flying. But, yes, 1000,000 lb aircraft is almost inconceivable, but does give credence to that old saying "....that with sufficient power you can get a brick to fly". But, I guess this video addresses the question "... Yes, but can you get it stopped?" Impressive for sure. Thanks for sharing Ed Edward L.

I think I used to hear numbers for gross weight on the B-52H models as topping out near 500K pounds. Here's a rejected take off test on the 747-8 loaded to nearly a million pounds. This is what you call "really hot stuff" . . . no pun intended. http://tinyurl.com/42lrcss Bob . . . ________________________________ Message 2 _____________________________________ Time: 07:05:54 AM PST US From: Subject: RE: AeroElectric-List: Re: Firewall pass through Dan, Those are nice. I've used the wire grip connectors which are also aesthetically appealing and are readily available at good prices.

Hmmmm . . . low level stuff . . . did your pilots have the pleasure of flying that so-called terrain avoidance radar? I worked on a crew tasked with aligning the radar's display processor (lots of vacuum tubes) on E and F models being recycled through Wichita for upgrades. It took 3 shifts to run the alignment procedure during which it was not uncommon to take 3 or more modules up to the lab for "repairs or adjustment". Those might have been infant mortality issues. It was a brand-new-out-of-the-box processor from Raytheon. I often wondered what the failure rate was for these things in the field. I hope that nobody ever had to fly head-down with one of those things in anger . . . it didn't take much drift to use up those 200' margins for clearing the hilltops and/or keeping your wing tips off the canyon walls!

Bob, I really can not recall for certain the reliability/reliance on those early terrain avoidance systems - best I recall they were acceptable - but at that time don't know too many pilots that actually trusted any "gadget" to keep them out of a hillside. I do know we had the terrain avoidance systems - however, for peace time exercising/training - the routine required for one of the pilots to exercise "eyeball terrain clearance" through the wind screen at all times. As best I recall, if we had ever gotten the "GO CODE", the thermal curtains would be pulled around the cockpit windshield - and flash goggles would be worn by the pilots. However, I do recall there were some situations where one pilot (the co-pilot naturally {:>)) was to pull away the goggle from one eyeball, pull back a portion of the curtains and keep one (presumably sacrificial) eye ball on the outside world. But, its clear that terrain avoidance has come a long ways since those days as have all things electronic. Ed From: Robert L.

For all the precise engineering and science in manufacturing, it boiled down to this. I was a navigator in the B-52H. So here's this 22 year kid, taking readings from the pilot, plotting the data points and drawing a line to determine the TA (terrain avoidance) correction feeling like he was inside the paint shaker at the ACE Hardware store trying to keep his lunch down halfway into a 16 hour mission. Precise? I'm just glad I didn't have a window. All kidding aside, we did have write-ups, but the overall feeling was that if it kept us below Soviet radar, it was worth the effort.

Roger that! I am convinced that this hobby has kept my 71 year old grey matter from eroding away - trying to stay up with the latest changes in just cell phones, Tablet computer, and other consumer products, much less microchips, lasers, solar cells, etc, etc, etc, is impossible, but certain is exciting to try.
