March 5, 2014 Rocket and Space Center and Beyond …

Writer’s Note

I have heard from a couple folks that they thought our exit for MN was quite harrowing.  I probably made too much of our delay due to air pressure gauges not working.  Motor coaches are just a big vehicle with truck-like systems and a house with house-like systems. Most owners are curious and want to know how things work and what to do when they don’t.  Some things are pretty easy to fix, sometimes you call for help.  There is an owner’s web forum (foreforums.com) (not part of the manufacturer) where people exchange ideas, questions, help and advise.  About 2,700 users and nearly 150,000 posts.  Lots of nice people and help when you need it.  So if I get too technical or too detailed please excuse me, it is just how I describe things.

This is one of the clumsiest programs I have ever used.  Inserting pictures is very slow.  Editing text makes no sense so far.  I have to try it in a Google Chrome browser to see if it is any different.  Please have patience. 

Space Camp

The Rocket and Space Center is pretty cool.  I was there in the early 70’s.  I was working on a NASA project to write simulation software for the recovery of the solid rocket boosters.  I have never actually seen one, even then.  And here they are!

There was a Saturn 5 rocket laying on its side, out doors.  Today there is entire building to house it and many more exhibits.

Here is the business end of the Saturn 5. It is about 35 ft across.  The five engines burn 12.5 tons of fuel every second!  The Saturn V rocket was about 140 ft tall.

There are three stages.  At the top of the third stage the Apollo capsule and the lunar lander were pushed into space and on towards the Moon.

The entire rocket was controlled by one of the most advanced computers of the day.  Once the rocket was released this computer controlled the engines, the trajectory, the stage separations, the orbital insertion and the push to the moon.

The display said that a stack of these computers about 2 miles high would be needed to have the computing power of a typical home computer of today.  Another way of looking at it is that a typical smart phone today has more than 100,000 times the computing power of what seemed like and amazing machine.

It is hard to get a sense of just how big this thing is. The Rocket Center is at the Army Redstone Arsenal. A lot of rocket testing was done here. The Saturn v engines were tested here before the first rocket launch. The test was so loud that it could be heard 90 miles away. 
One of the Space Shuttles was there.  Not one that ever flew in space but it was just like the real thing.  The main fuel tank and the solid rocket boosters were real ones as well.
 

It was a great place to stop and visit.  And I got to see a real Solid Rocket Booster (SRB).  By the way the SRB with parachutes attached and open was taller than the IDS building.  

Tuskegee Airmen National Historic Site
After leaving the Rocket and Space Center we drove down to Auburn, AL (go Tigers) to a Camp Wal-Mart.  We walked laps, got some milk and fruit and walked some more.  About 4:30 in the morning something outside was making a lot of noise.  It sounded like a giant sander.  We think it was some sort of vacuum cleaner for the parking lot.
We drove about 14 miles to the Tuskegee Airmen NHS.  This is located at the Moton airfield which was built to train pilots, air crews and ground crews.  Segregation and discrimination were the way the Army Air Force worked at the time and many in the Army refused to give African Americans a chance.  Well, these Airmen proved to be a strong force during WWII in Africa, Italy, bomber support and all the way to Berlin.  More than 16,000 were trained as pilots, air crew and ground crew personnel.  
The exhibits we housed in the two original hangers.  The rigors of training for pilots, mechanics, ground crew and all the other support people looked hard.  Typical pilot training was more than 9 months, longer than the life expectancy in combat.
 

Pilots learned to fly in Stearman biplanes then went on to more advanced training aircraft and finally into fighter training at bases all over the US.  Some split off to become bombardiers or navigators.   














By 1944 the RedTails were flying P-51s.  It wasn’t easy for them to convince the army that they needed better airplanes to fly the long range bomber fighter cover missions they were being assigned.  Eventually they got P-51s and provided some extraordinary service. 






After a really worthwhile visit were headed off toward Florida.  Our arrival in the next post

Day 2 – Bloomington, IL to Huntsville, AL

This was a long driving day at least for us.  About 9 1/2 hours including the obligatory stops. We left Camp Wal-Mart early after a lap or two around the store. It was maybe 7 degrees. I still had the long undies on but just a flannel shirt instead of a sweater.  Driving was good until southern IL where the effects of the storms over the weekend became evident.  Remember we left late, good thing.  Lots of snow on the sides of the road, the shoulders were rarely cleared.  By Paducah, KY we were down to one lane and the other lanes was covered in a solid, heavy layer of ice.  No passing here.  Then there was the construction.  Lots of slow downs. Never saw a construction worker or piece of equipment operating.  The huge bridges over the Ohio, Cumberland and the Tennessee Rivers are all down to a single lane each way.  Probably ready to fall into the river.

So we went slow at times and carefully at all times. The coach weighs 34,000 lbs and the Jeep another 3,400 lbs.  We move carefully.  We sit up high so it is easy to see what is coming.  Our mirrors are great so visibility is good.  We try to help each other out looking for oncoming traffic in the on ramps and when we are changing lanes.  We are a team!

Into Tennessee and the roads got worse.  Lots of times it was less than one lane and everything else was ice.  Heading into Nashville the trees were covered in ice, whole trees and big limbs were down everywhere.  Water had oozed out through layers in the cut rock faces along the highway and frozen into shaped that looked like candle wax. There was a dense fog layer just above us and visibility was OK but very frosty looking. The north bound lanes had a stop and go back up for more than 10 miles.  There were several broken down semis and even a Greyhound bus. Many cars in the ditches. We saw two major semi wrecks. On the last big downhill into Nashville the roads started to clear up, the fog was lifting, the tree ice was going away and there was no more snow on the ground. On we went. 

We were going to stop at another Wal-Mart south of Nashville but we did the math and figured we could get to the Space and Rocket Center near Huntsville, AL before dark. We made it with minutes to spare.  I have never seen traffic like that heading west from Huntsville.  There was one exit at Madison where the traffic was backed up, two lanes wide, for at least four miles.  We found the exit for the Rocket Center and headed into their RV Camp.  Pretty old but serviceable.  It was about 60 degrees so we flushed all of the winter antifreeze out of the coach water system, added water with a fairly high bleach concentration, flushed all of the lines out with that.and then added another 40 gallons of water. I washed all of the mirrors and the windshield.  Lots of road grime.  All of that was done shortly after dark.  Supper, some chores, some reading, some email and we were off to bed by 9:30.  It is warm, cozy, very comfy and quiet in the back bedroom.  After a day of driving there is residual engine heat as well.  We sleep very well.

My next post will have some pictures from the Rocket Center.  There are some great exhibits there including a Saturn 5 rocket of the type used to send men to the moon.  It had some of the most sophisticated computer systems available at the time.  Maxed out it had less than 5 megabytes of RAM.  The display stated that it would take a stack of memory and processors from the Saturn 5 more than 2 miles high to equal a typical home PC of today.Today’s smart phones have more than 100,000 times the computing power that those giant rockets had.  And those seemingly primitive computers controlled all aspects of the rocket’s flight after lift off. Pretty amazing.  More later …

We Are Off, March, 2014. SE USA

Day 1, Monday, March 3, 2014
We were going to leave on Saturday but the weather in southern IL and TN looked bad. Snow, sleet, ice and even rain. So as is not uncommon for us we waited until Monday for things to clear up just a bit before the next big storm shows up.

It was -19° this morning.  A few last minute things to load up. Some house chores (turn off the water and so on) and we should have been ready to go.

We opened the door on the barn and the old girl started to whine.  A little coaxing and after all was ready she started right up.  Of course the engine heat was on all night as was heat in the coach and the refrigerator.

When it was up and running I noticed that the two air pressure gauges read zero and both had warning lights on.  a quick check of all of the systems that use compressed air showed that all were working.  Good thing, these include ride control, ride height, brakes, emergency brakes and so on.  Actually, if there is not enough compresses air you cannot move the coach.  The emergency bakes will not release, the transmission will not engage, the ride control system will disallow movement, dead in the water (or snow).

A quick check at the Foretravel owner’s website and I got quick answers.  The gauges are electric and are fed from pressure transducers in the “blue module” which has been problematic for many owners.  This is a custom electronics device that was only used for 4 model years, ours included.  The solution is to use actual pressure gauges fed from the lines leading to the “blue module”.  A project for some other day.  I may have to spend some time trying to shut off the dinging alarm that goes off because the gauges are not getting a signal.

Everyone said that if all else was working go for it.  So we took a five mile test drive to confirm everything was working, it was, so we hooked up the Jeep, checked all of the lights and hit the road about an hour later than we were anticipating.

We had the coach heat on, the dash heat on, our long undies on and our jackets on and it was cool but OK.

So on day one we drove to Bloomington, IL.  About 440 miles in 8 hrs including several rest stops for driver changes and well, bathroom breaks.  Roads were good, no weather issues other than it was cold and we just made it to Camp Walmart as sunset was nearing.  I got to try out my new HID European headlight bulbs.  I don’t know what that means but they are two or three times as bright.  

I swore I would never drive in the dark again after going through Kansas City after dark last winter.  I am going to try to keep that promise.

And so another day comes to a close.  still smiling.  We got in three store laps at Walmart and got some fruit for breakfast.  we had pretty much our choice of the parking lot.  We were warm and snug in our jim-jams.  We watched the first episode of Foyle’s War, had a couple of fig Newtons and called it a day by 9:30.  More tomorrow, I hope.  This blogging thing is not as simple as it should be.

2014 Travels

SE USA

It is March in one of the worst winters we can remember (there have been others just as bad, we just choose to forget them) and we are eager to hit the road.  The coach is packed and fueled.  The refrig is on.  The heat is on. Everything is ready but the weather along the route we will be taking heading towards Florida.  Snow, rain and ice in southern Illinois and Tennessee. Prudence says we should wait until Monday to leave.  So does Susan.  I agree.  So we wait a couple days.  Just like our first long trip in the original Home2.
