Leaving El Paso

We’re sitting on the C-9 here at Biggs and the engines are humming. We’re a few minutes away from take off, heading to Kelly Field at Lackland, near San Antonio, Texas. We should get in there at about 9:00 local time. Yep, Texas is really so big that we need two stops to get across it.

We’ll get fuel at Kelly and then continue on to Columbus Air Force Base in Columbus, Mississippi. It looks like we’ll get there at about 1:00 CST.

So here is the schedule so far:

Biggs (El Paso, TX)       Leave: 6:15 am local time
Kelly (San Antonio, TX)   Arrive: 9:00 am local time, Leave: 11:00 am local time
Columbus (Columbus, MS)   Arrive: 1:00 pm local time

Hope that helps. I’ll update it if we get new info.
Here’s a shot of Atlantis and the SCA getting ready to roll out behind us.

I “borrowed” a bunch of pictures from our NASA photographer, Ben Smegelsky so throughout the day I’m going to go back and snap them to previous posts. Some of them are pretty nice so you may want to go back and check them out.

Putting Together the Flight Schedule Puzzle

Right now the team is hunkered down in a conference room here at the hotel pouring over data sheets and weather charts. Underneath the chatter of the discussions you can hear them clicking and clacking away at laptop keyboards and calculators. So far everything is looking good and we should have a flight route for tomorrow soon.

I’ve been reading the comments and one of the most popular questions is, “when is Atlantis flying over my town?” It’s not as easy as you might think to answer that question. In order to get the shuttle home to Kennedy Space Center, we have quite a few rules and restrictions we have to follow.

First of all, we have to be very careful about the kind of weather we fly into and out of and through. And as you all know, forecasts change all the time. Flying from Southern California to Central Florida we are really dealing with weather planning across the entire southern half of the US — and meeting all our other strict constraints on temperature, clouds and precipitation. Put all of that together and you can see why it’s tough to say where we’re going to be and when we’re going to get there.

Today’s first leg flight is a perfect example of how crazy the scheduling challenges can be. We had originally planned for just a fuel layover in El Paso, then added an option to go north to Amarillo instead of El Paso and finally needed to pick just stopping at El Paso for the day.

Here’s what Ferry Operations Manager, Don McCormack said about it. He can explain it better than I can…

This is a good question that doesn’t have a quick easy answer.

First of all, we start with a list of airfields (about 20), primarily military bases that are on an approved list of airfields to be used during a ferry mission.  Each of these bases has agreed to accommodate an SCA/Orbiter landing and each has personnel trained to do so.  There is a very specific set of requirements that must be satisfied by each base.  These requirements include providing security for the Orbiter, providing a safe place to park an Orbiter that still has highly toxic commodities on board, has ground support equipment that can reach the Orbiter on top of the SCA if it is required, and not least of all, is willing to accept the disruption to normal operations that is caused when we arrive.  In addition, if the ferry stop is overnight, the base also arranges for transportation and lodging of the ferry team.

Second, the Orbiter has a very restrictive set of atmospheric/weather requirements.  We must, at all cost, avoid rain in flight.  Flying through rain will damage the Orbiter’s thermal protection system and result in a costly and long delay before the Orbiter’s next flight.  We also try very hard to avoid exposing the Orbiter to severe weather on the ground, which could also cause damage.  The Orbiter cannot be exposed to temperatures less than 15 F either in flight or on the ground and the Orbiter cannot fly at an altitude where the pressure is less than 8 psia.  These requirements typically limit our altitude to an 11,000 to 16,000 ft range.  So, the SCA/Orbiter route is largely driven by the bases that are available and the weather en route.

In addition, the SCA has a very limited range when ferrying the Orbiter.  That range depends primarily on the weight of the Orbiter and the air temperature.  Winds are also a factor.  The heavier the Orbiter is, the less fuel we can load into the SCA, pure and simple.  Without going into a lot of technical details, hotter air is less dense air and that too significantly impacts the performance of the aircraft.

Finally, hardware issues can also impact our route selection by causing delays.  During delays, the weather changes and often times so does the route.

So, there are many factors that drive the route we take with weather being the big one.  And as everyone can understand, predicting the weather is not an exact science.  That’s the biggest reason that it’s often the morning of the flight before we can say, with certainty, where we’re going.

I told you he knew his stuff.

Deep in the Heart of Texas

Okay, maybe not geographically the heart of Texas, but close enough. We landed at Biggs Army Airfield near El Paso, Texas. The flight seemed really quick and I’ll tell you something, flying with NASA pilots beats flying commercial any day. These guys don’t mess around! If we’re banking left, we are BANKING LEFT!

NASA pilots are also patient enough to let me take their picture while flying.

The pathfinder plane that we were all flying in is a NASA C-9 airplane. We had the weather officers and quite a few from the shuttle team on board with us and we were flying about 100 miles in front of Atlantis and the SCA. Here’s how the C-9 looks from the outside.

Here’s what it looks like on the inside. Not necessarily plush, but they did pass out Fritos and soda.

Like I said, we’re in Texas at our first stop. We landed here at Biggs at 11:22 am MDT. The shuttle team now has meetings all afternoon where they’ll keep a close eye on the weather forecasts and plot out the rest of our route. Here are some pics and a quick video of Atlantis and the SCA landing. 


We’re going to stay here overnight and if all goes as planned and the weather cooperates we’ll be on our way in the morning. 

The early morning.

Space Shuttle Atlantis' Ferry Flight Now Under Way

Space shuttle Atlantis’ ferry flight is under way! The modified Boeing 747 Shuttle Carrier Aircraft carrying Atlantis took off from Edwards Air Force Base in California at 11:06 a.m. EDT. The Shuttle Carrier Aircraft is heading to Biggs Army Air Field in El Paso, Texas, and is expected to arrive about 1:10 p.m. EDT. The shuttle and the ferry flight team will stay at Biggs overnight and then continue on tomorrow morning to NASA’s Kennedy Space Center.

By the Dawn's Early Light

We were up early this morning for the weather briefing (although maybe not as early as I had initially made it seem) and everything is looking good. We are scheduled to take off a little later than we had planned, so we are only going to make one leg of our four-leg trip.

In the comments a lot of you are asking about when we’re leaving and where we’re headed. While tomorrow’s stops are not solid yet, (weather makes us keep plans very fluid), we know today we will leave Edwards at 8:00 PDT, flying south and passing over Lancaster and Palmdale, California. We’ll also be doing a fly-over at Las Cruces, New Mexico. Weather is going to let us go as far as El Paso, Texas today and we’ll see what the schedule is for tomorrow.
