This plane is so tricked out!

“Wow, wow, wow, wow! This plane is so tricked out!” I was instantly smacked in the face by total coolness overload. The awesome factor just freaked me out. I must have said “Wow” at least fifty times. Before yesterday, I’d often described NASA’s Airborne Research Program as “a collection of NASA planes with NASA instruments on them,” but hey, that was before I’d actually boarded one.

To get ready for flying on this airborne mission, the Student Airborne Research Program (SARP), I read up on the aircraft, a “modified DC-8.” The info seemed straightforward enough. I viewed some animations of the plane’s configuration, and filled out a bunch of paperwork, but nothing could have prepared me for the moment I first stepped foot on that plane.

Collecting air samples
Collecting air samples at altitude to be brought back to labs on the ground.
A “modified DC-8,” you call it? Hah! The term “modified” doesn’t even come close to describing this marvelous winged beast, every inch of which has been fully customized to work as a flying science laboratory. Wanna hear about it? I’ll bet you do.

Of course there were more large computer systems, collection canisters, science instruments, navigation and coordination consoles and other equipment than I could ever have imagined, but it was the smaller details that really struck me. For example, many of the typical cloudy, yellow commercial aircraft windows had been replaced by panels with tubes and valves for collecting air samples at altitude. They stuck out of the holes where the old windows had been. There are also holes on the bottom of the plane for the radar instruments. I sat near a type of optical window, which was maximized for clear viewing and bolted into the fuselage.

Checking the flight path

Another thing I thought was cool was that literally three minutes into the flight, one of the mission managers announced, “OK, time to get up out of your seats, get moving and go to work.” As someone who hates sitting still, I was like, “This is fantastic!” Within moments the plane was crawling with scientists taking measurements of carbon monoxide, ozone and carbon dioxide and filling racks of canisters with air samples to take back to their lab on the ground. (Learn more about the SARP science here.) Flight project coordinators were busy communicating with science project coordinators and the pilots over the headsets to make sure the science objectives were achieved.

Taking measurements at low altitude
One of the science objectives was to take measurements while flying at low altitudes.
I took a turn in the cockpit for a while to spend time with two pilots and a flight engineer. The science required us to fly as low as 1,000 feet over the Sierra Nevadas along multiple prearranged flight paths. Remaining at a constant altitude while flying over mountains with extremely variable terrain meant these pilots had to tuck in and really fly the plane (as in “Pay attention, y’all! There ain’t no autopilot- or cruise control-kind of flying.”)
