The June 2016 medevac was first announced in this NSF press release issued on 15 June South Pole time (UTC+12, 14 June US/Canada Mountain Time) after the two Kenn Borek Air (KBA) Twin Otters had departed Calgary. The press release included the key statement, "After comprehensive consultation with outside medical professionals, agency officials decided that a medical situation at Amundsen-Scott South Pole Station warrants returning a member of the station's winter crew to a hospital that can provide a level of medical care that is unavailable at the station," and it was accompanied by the above file photo from the 2003 medevac...and of course that photo appeared in many other media reports that day.
Interestingly, Wallace ("Wally") Dobchuck, who would be the lead pilot on the evolution, first learned about the possibility of the medevac about a week before it began...when he was at a review meeting in Boise with NSF where plans for Kenn Borek's upcoming season were to be discussed. Wally returned to Calgary where plans were being made and crews were being selected; on Saturday 11 June they were informed that the mission was on.
On the 14th, the two aircraft left Kenn Borek headquarters in Calgary, first flying to Centennial airport, south of Denver near the ASC offices. Here they picked up some essential mission equipment. They then continued on to McAllen, which is along the Rio Grande in far southern Texas. From this point, relief crews flew the Twin Otters south to Punta Arenas, while the primary crews continued south on commercial aircraft, so as to arrive well rested.
The Twin Otters stopped in Liberia, Costa Rica as well as more than once in Chile, before reaching Punta Arenas (at right, a route map from this blog post about the medevac by 2012 IceCube winterover Carlos Pobes). This part of the timeline is not well documented... presumably the flight crews reached PA on commercial flights before the Twin Otters did, and had some extra down time. In any case, by the time the primary flight crews took over the Twin Otters, it was late evening in Punta Arenas, I'm thinking about 2200 local time (UTC-4) on 17 June, or 1400 South Pole time (NZST, UTC+12) on 18 June. (All times are SP times unless otherwise indicated). Punta Arenas and Rothera time is UTC-3). The primary air crews had arrived earlier and had about 36 hours rest before the next leg. Meanwhile, the two Kenn Borek medics had also arrived in PA.
But...the weather closed in with a blizzard at Rothera, so the crews waited around for 2 days before finally heading south in the early morning (PA) hours of 20 June. They arrived about 6 hours later while it was still light enough to reconfigure both aircraft... including switching out their wheeled landing gear for skis (NSF press release announcing the arrival at Rothera--which also included the BAS file photo (left) of Rothera). After resting overnight, the next morning it looked like there would be a 48-hour weather window for a planned ~30 hour return trip to Pole. The primary flight crew, consisting of pilot Wally Dobchuck, copilot Sébastien Trudel, aircraft maintenance engineer Michael McCrae, along with medic Thai Verzone, left Rothera at about 0800 local time (UTC-3) on Tuesday 21 June (0100 SP time on Wednesday 22 June. The aircraft carried 7,000 lbs/1,000 gallons of fuel, including 2 250-gallon tanks in the fuselage, as well as 2 55-gallon drums. Things were a bit dicey early in the flight, as the weather had started to deteriorate, and it took a couple of hours for the aircraft to burn off enough fuel to be able to ascend above the icing zone. If this had not happened, Michael could have opened a valve to dump 1,500 lbs/~225 gallons of fuel...but this probably would have required a return to Rothera.
One of the details of the flights to/from Pole that was revealed later by the flight crew, is that they got caught up in singing the song "In the jungle...the lion sleeps tonight" despite not knowing all of the words. That tune has been recorded many times since it was written by a South African of Zulu origin in the 1920's (Wikipedia article)...it was more recently made famous by the Lion King movie.
Meanwhile, preparations at Pole had been underway for awhile, lots of work for everyone on station:
[Robert Schwarz was the only person on station authorized by NSF to share photos
with media during the event; accordingly all of the Pole photos on this page are his.]
|Some of the stuff had to be dug out from the "end of the world" storage berm, including a warming hut, generator and electrical building, pump house, and a fuel manifold building. All of which had to be hooked up and tested.
Eleven of those burn barrels were prepared and set out by Max Peters. They were 55-gallon drums cut off to 14" high and filled with a mixture of JP-8 and mogas as well as some pieces of wood. Tests proved that with 15 gallons of the fuel mixture, they would burn for 7 hours. It took about 30 seconds with a MAP-PRO torch to warm the fuel enough so that it would ignite. And they were visible from the aircraft 15 miles away. Back in my 1977 winter there were several dozen Coleman lanterns on shelves in the garage arch, provided for use of an emergency winter medevac...it was a good thing we didn't need to use them for that purpose, as they didn't burn for very long in winter temperatures. Additionally, there were various red and white LED strobes, including 5 bright headlamps that Robert had ordered from Amazon for use on sailing trips. He set these up inside of insulated boxes heated with bottles of boiling water, and used inflated trash bags for diffusers.
Testing it outside of DA. Here's Robert's video of the test.
Other preparations were underway inside the station: to prepare for a potential emergency rescue, fire, or other situation, two snowmobiles were brought inside of the heated LO, along with two Nansen sleds that were loaded with emergency supplies, including sleeping bags, several fire extinguishers, and medical supplies. Needless to say, the snowmobiles would not have been usable if they had been parked outside. Fortunately, this equipment was not called upon during the medevac evolution. And I must say I'm impressed by the handlebars on those Nansen sleds...back in the day (1977) the normal means of propulsion for these sleds was...us.
A view of the lit-up skiway from the NOAA webcam about 2 hours before the medevac flight arrival (the time stamp is UTC,
12 hours earlier than Pole time, which was 08:04:55 on 22 June). Note the excellent weather and visibility--the Moon was up,
just past full, and there was not much wind.
Robert Schwarz and Matt Krahn spent many hours on a snowmobile setting out the various strobe lights about an hour before the landing, picking them up afterward, and then setting them out again before takeoff in case the aircraft had to return and land.
[The need for the bamboo mats was learned during the April 2001 medevac. Due to the temperature (-95ºF/-70ºC), "extreme measures" were required to break the landing gear free (screen grab from Steffen Richter's video).]
The temperature when the aircraft landed was -75.6ºF/-59.8ºC.
Securing the aircraft took about half an hour. This included closing things up and setting up some heaters to keep the electronics and engines somewhat warm. After that, the flight crew headed into the station for a welcomed dinner of bison steak (extras from the midwinter dinner), well prepared by head chef Darby Butts and the rest of the galley crew. The flight crew then headed off to bed...using oxygen concentrators as Twin Otter crews normally do during their RON at Pole. Meanwhile, the Polies were enjoying the freshies from Rothera--boxes of apples, oranges, and tangerines, as well as sweets--tarts and biscuits (well, English biscuits aka cookies or brownies perhaps) and 900g of homemade Antarctic sea salt for Darby to do things with.
Eight hours after the landing, preparations began for the northbound flight.
The main flight crew met the medevac patients in one of the main hallways, shortly before the crew headed out to get the aircraft lately. Pilot Wally Dobchuck explained to them what would be happening--the patients would be on stretchers with limited headroom--meanwhile, the 2 55-gallon drums of extra fuel had been removed from the aircraft to compensate for the weight of the patients, medical supplies, and the one bag that the passengers could take with them.
The Twin Otter departed Pole at about 1945 22 June and headed to Rothera, as described in this Washington Post article which was updated on 22 June EDT. The flight was uneventful ("all downhill" as it were), perhaps my only concern while reading the accounts was that Darby Butts and the rest of the Pole galley crew had provided the flight team with some very spicy Thai soup. It was greatly appreciated by the entire flight crew. Fortunately there was no need for an emergency Antarctic landing to deal with any unanticipated side effects of the soup (!) although this had been one of my worries at the time.
At left, the two aircraft on the Rothera runway...the one with wheels would shortly take the patients to Punta Arenas. About a month after the medevac, I met up with friend Michael Powell, who had been the BAS base commander for Rothera in 2001 when Ron Shemenski had been medevaced. He said that it was fairly easy to add (or remove) snow from the runway as needed to facilitate landings with skis or wheels...and that there also was a second snow runway behind the base that could be used for ski aircraft operations. (This BAS photo appeared in various news articles from AP, including this archived story with photos).
After everyone had returned home, more stories and videos started to emerge. One of the best sources is CTV News...in this 5 July 2016 story they present nine videos featuring interviews of the flight crews.
Here's the Pole flight crew as they were being interviewed in the KBA hangar after their return to Calgary. From left: aircraft maintenance engineer Michael McCrae, copilot Sébastien Trudel, and chief pilot Wallace (Wally) Dobchuck. This is another screen grab from that Smithsonian video mentioned below.
Dr. Hamish Wright, the 2016 wo physician from New Zealand, was praised by outgoing President Barack Obama for his contribution to the medical evacuation, per this 21 January New Zealand report from Newshub.
The Kenn Borek aircrews received two additional prestigious national awards in March of 2017. The first was the Aviation Week and Space Technology Laureate for Heroism, presented on 2 March (Aviation Week article and associated video from NSF. The second of these was the 2017 Trophy of Current Achievement, presented by the Smithsonian's National Air and Space Museum--the eight crew members were presented with the award on 29 March at a black tie dinner in Washington DC...per this NSF press release, this CBC News account with video, and this extended video from the Smithsonian National Air and Space Museum. The honorees included the Pole flight crew and medic pictured above, backup medic John Loomis, and the flight crew that flew the patients from Rothera to PA--pilot Jim Heffey, copilot Lindsay Owen, and aircraft maintenance engineer Gerald Cirtwill.
