an enemy on a more local scale. But something about the EMP attack story didn’t sound quite right.
“Wait a minute, guys,” I transmitted, “an EMP attack wouldn’t knock out our GPS satellites. I think it might be something else, like sun spot activity.”
“This is Delta 883. You’re right, WorldJet Airways. I’ll pass this up ahead and see if anyone has any more information.”
I heard Delta relay my message, then I heard an intermittent, scratchy retransmission from an airplane ahead of him. Maybe one of the planes ahead of us would get more information. We had our own airplane to worry about.
“Jim, do you have the WBM?”
“Here you go, boss.”
I looked at all five pages of the Weather Briefing Message. It was like I always said: I’d rather be lucky than good. Severe clear weather over the entire eastern half of the United States, from Colorado east, for the next two days. A winter storm was predicted in a couple of days, but right now it was smooth sailing. This was great news. If the power grid was out, there was no telling if the backup systems at all the airports would be operational. We may have navigation signals, we may not. At least it was daytime, and the weather was good. We’d be able to make a visual approach to wherever we were going to land.
Chicago O’Hare Airport, our destination, was always hectic, even when communications were working. Even on a good day when everything was going smoothly, the ATC controllers usually sounded more like tobacco auctioneers than tower operators. If there was any snag in communications, it was going to get pretty hairy.
I looked at the O’Hare forecast. The wind was going to be from the west. At an airport that’s not very busy, that would most likely mean landing to the west. At O’Hare, unless the wind was greater than 10 knots, takeoff and landing directions were not so set in stone. My guess was that we’d be using Runway 32 Left, 32 Right, 27 Left or 27 Right. Depended on which runway they were using for takeoffs.
But wait. If communications were out, there wouldn’t be any takeoffs. Only landings. That meant our potential conflicts had just been cut in half. Things were starting to look up. I turned to Jim and Mark.
“Okay, guys, I think there’s been some kind of event that’s taken out most of the radios and the power grid. Is anything else on the airplane inop?”
“The only other thing I noticed is the EFBs aren’t working,” Jim said. “I think they quit around the same time as the GPS.”
I looked down at my Electronic Flight Bag. The screen was black, unpowered. Unlike when we carried 40 or 50 pounds of paper charts and maps in our “brain bags”, the leather catalog cases pilots had carried since the beginning of commercial aviation, all of our flight documents were now in our EFBs, with backup copies in the iPads we’d recently been authorized to use in the cockpit.
I looked on the overhead circuit breaker panel and found the EFB-L and EFB-R circuit breakers and pulled them out. One potato, two potato, three potato. I pushed them back in. It would take a few minutes to see if recycling the breakers would get the Left and Right EFBs back in operation.
“Jim,” I said, “check your iPad. We may need to use the charts in there.”
“Bad news, Ham,” he answered. “I tried cranking it up a few minutes ago, and all I got was a black screen with the Apple logo. I tried both of the others, too, and none of them are working.”
“Hamilton,” Mark said, “why would some of our equipment work and some not?”
“Most of our electronics,” I answered, “are in the lower electronics bay. That area is well shielded, and the airplane itself acts pretty much like a Faraday cage. The electronics in the cockpit, like the iPads, aren’t so well protected because of all of the windows. My guess, and it’s just a guess, is that there was some form of event, like a sun spot, that caused a glitch. When we get closer to land, within radio range of the States, we’ll try Guard frequency. I suspect that Guard transmitters have some sort of power backup, and they’re probably well shielded. We’ll just have to wait.”
Mark and Jim silently nodded. After about three minutes, the EFBs came back to life. At least we’d have our charts. It was going to be at least three more hours before we were within range of any American or Canadian radio stations.
It was going to be a long three hours.

It was time to give ATC a call on Guard frequency. We were still over the ocean, but, I estimated, we would be in range of one of the radio facilities on the east coast.
For the previous three hours we had maintained a listening watch on VHF 123.45, and had passed along our information, sparse as it was, to aircraft following us. If this had been a domestic flight, we would have come into contact with aircraft that were headed east, but the NAT tracks only operate in one direction. Flights on the tracks go east at night, usually to arrive in Europe around the time the airport control towers accept arrivals, typically 0600 local time, like Heathrow. Westbound flights operate in the daytime.
From what I could determine, all of the airplanes I had made contact with had exactly the same indications we had, in terms of inoperative equipment. Fortunately, our TCAS was working, since it was dependent only on the operability of onboard equipment. That meant we would be able to visualize nearby aircraft on our TCAS display, and we would all be able to maneuver to avoid midair collisions with other TCAS-equipped aircraft. At these high altitudes, all aircraft were required to have TCAS. It might be a different story altogether when we got lower, as we approached to land, since light planes didn’t usually have that equipment. But I suspected there wouldn’t be any light planes flying by the time we got to Chicago.
We had a fairly lengthy discussion about exactly where we should land. Given that the meteorological conditions were virtually the same everywhere, arrival weather would likely not be a factor. There was the real potential that, wherever we went, we might not get a gate at the terminal. That would mean remote parking.
The problem with remote parking was that we might not be able to get off the airplane. The 777 sits so high that it takes a special loading bridge or portable stairs to reach up to the aircraft door sill. If we were to divert to an airport that didn’t routinely accept 777s, we could have a problem with our passengers trapped onboard.
That’s what happened when I was flying a trip on September 11, 2001. Like today, weather was crisp and clear all over the United States. When the national aviation emergency was declared, every aircraft was told to land immediately at the nearest airport.
At the time, I had only been a 777 Captain for two years. Two years may sound like a long time, but the 777 is a highly sophisticated airplane, and it takes quite a bit of time for a pilot to fill his bag of tricks on a new airplane. I was flying a domestic trip, from Washington Dulles Airport to Denver International Airport. We were over Kansas when the national emergency was declared. It seemed like a no-brainer to me to continue to Denver, but when the controllers said land immediately, they meant immediately. The closest small blue circle on my cockpit moving map display, denoting a suitable airport, was labeled “KFOE”. From my Boeing 727 days, when I had flown nothing but domestic trips all over the country, I had remembered that FOE was the VOR identifier for Topeka.
With some great help from my copilot, I had scrambled to program Topeka into our FMC to enable the pressurization system to schedule properly, located the paper approach charts for Topeka that I carried in my “brain bag”, the catalog case that carried all of my documents, and set up for an immediate landing. As I extended the speed brakes and executed an emergency descent, my copilot had made a quick Passenger Address announcement advising everyone on the aircraft that we were making an emergency landing at Topeka.
When we landed at Topeka, the Ground controller advised us that the loading bridges could not accept any aircraft larger than a 727, so we would have to deplane remo
tely. Then they told us that the only portable stairs they had would be three feet short of our door sill. I still remembered, now eleven years later, how I had stood on the top step of the portable stairs and helped the passengers deplane, one by one. We had three wheelchair passengers that day. It was grim.
I wasn’t going to let that happen again today, if I could help it. The passengers already were aware that something was wrong. About a half hour after the glitch happened, the purser came up to the cockpit.
“Captain, is there something going on that I need to know about? One of our passengers noticed that our airplane symbol isn’t moving on the Airshow moving map display on the passenger video screens. He did a pretty good impression of Scotty from Star Trek when he said, ‘They have us in a tractor beam.’ Anything wrong besides the Airshow?”
“We’re not sure, Bill. We’ve lost contact with our GPS satellites, and with all ground-based communications facilities. We’re hearing from other airplanes that the power grid is out all across the United States. Right now, we’re planning on continuing on to O’Hare, but that’s subject to change. I’ll keep you posted as soon as I hear anything new. I’ll make a PA announcement to let the folks know what little I know.”
“Thanks, Ham.”
Bill was one of the few Flight Attendants that could
