Wop May Wilfrid Reid " Wop " May , OBE , DFC ( March 20 , 1896 – June 21 , 1952 ) , was a Canadian flying ace in the First World War and a leading post - war aviator . He was the final allied pilot to be pursued by Manfred von Richthofen before the German ace was shot down on the Western Front in 1918 . After the war , May returned to Canada pioneering the role of a bush pilot while working for Canadian Airways in Northern Alberta and the Northwest Territories . Early life . May was born in Carberry , Manitoba , son of a carriage maker . His family moved to Edmonton in 1902 , and while on the way they stayed with family and friends , and his two - year - old cousin , Mary Lumsden , could not pronounce Wilfrid and called him " Woppie " . This gave him his nickname " Wop " . First World War . May joined the Army in February 1916 during the First World War . He rose through the enlisted ranks to sergeant , and spent most of 1916 as a gunnery instructor . In 1917 , his battalion , the 202nd battalion C . E . F . ( Edmonton Sportsmen ) , was shipped to England , where he and his friend Ray Ross applied to join the Royal Flying Corps . His first flight resulted in the destruction of both his own and another aircraft ; nevertheless , the RFC accepted his applications and May resigned from the Canadian Army . After initial training in London in October , he was moved to a fighter training squadron and graduated in February 1918 . On April 9 , 1918 , Lieutenant May was transferred to No . 209 Squadron of the newly created Royal Air Force ( the squadron being a unit of the Royal Naval Air Service until April 1 , when the RAF was created ) . The squadron was commanded by another Canadian , May ' s former school friend Roy Brown , who had never lost a subordinate pilot . May spent most of April getting used to his Sopwith Camel . On April 20 , 1918 , May fought his first aerial combat . The German Fokker Triplane crashed of its own accord during the brief fight . Death of the Red Baron . The following day , April 21 , 1918 , saw 209 Squadron again on patrol . Due to his inexperience , Brown gave May similar instructions as before – he was to stay out of the fights and simply keep an eye out . Around 10 a . m . the squadron attacked a group of Triplanes . During the dogfighting , May circled above . But when he spotted another plane doing the same thing he decided to launch an attack . May chased the aircraft which fled into the middle of the dogfight . But when his machine guns jammed , May quickly dived out of combat . Unknown to anyone , May ' s target was Wolfram von Richthofen , cousin of Manfred von Richthofen , the " Red Baron " . Wolfram had also been given orders to sit out above the fight and watch because he was a novice flyer , too . On seeing his cousin being attacked , Manfred started to chase May as he turned to pull out of the dogfight with jammed guns . Roy Brown , who was flying above , also noticed the Red Baron peeling off to attack May . Diving in from behind , Brown intercepted von Richthofen ' s red Triplane . May noted in his combat report : 21 / 4 / 18 Camel D3326 90 minutes Engaged 15 to 20 triplanes - claimed one . Blue one . Several on my tail , came out with red triplane on my tail which followed me down to the ground and over the line on my tail all the time got several bursts into me but didn ’ t hit me . When we got across the lines he was shot down by Capt . Brown . I saw him crash into side of hill . Came back with Capt . We afterwards found out that the triplane ( red ) was the famous German airman Baron Richthofen . He was killed . Who actually shot down the Red Baron remains a subject of much dispute . May continued flying with 209 Squadron until the end of the war , and eventually claimed one destroyed and one shared aircraft captured , six destroyed with one shared , and three destroyed and one shared " out of control " . He was awarded the Distinguished Flying Cross in 1918 . He relinquished his RAF commission on May 8 , 1919 with the rank of captain . Postwar career . After returning to Edmonton at the end of the war , May and his brother rented a Curtiss JN - 4 " Jenny " and started May Airplanes Ltd . , opening Canada ' s first airfield ( or aeroport ) in a rented pasture in the neighborhood now known as Mayfield . They appeared at various functions during 1919 , and would now be considered to be one of the first barnstorming companies in the world . In September 1919 , May Aeroplanes was hired by the Royal Canadian Mounted Police ( RCMP ) during their manhunt for John Larson , wanted on two counts of murder and a break - in . May flew Detective James Campbell to the small town of Edson , and Larson was caught soon thereafter . They were soon joined by George Gorman to become May - Gorman Airplanes Ltd . and took delivery of another Jenny ( built by Standard Aircraft ) in which George delivered the " Edmonton Journal " newspaper to Wetaskiwin , 45 miles south of Edmonton . May and Gorman were hired by Imperial Oil Limited to fly two Junkers airplanes , equipped with skis , from New York to Edmonton in early 1921 . Imperial Oil planned to fly these planes into the Northwest Territories to service its proposed oil developments along the Mackenzie River at what later became known as Norman Wells . In March , Gorman and Elmer Fullerton flew these two planes across the 60th parallel ( the first ever flight into the NWT ) into the Canadian sub arctic proving that aircraft could operate in sub - zero temperatures . This was the start of aerial exploration in the most distant parts of Canada . In 1924 the business failed , and May married Violet " Vi " Bode in November . He decided to get a " real " job , joining National Cash Register in Dayton , Ohio where he went for training . While working on a lathe he was hit in the eye by a shard of steel , and from then until 1938 he began slowly going blind . Convinced that flying really was his calling , he formed the Edmonton and North Alberta Flying Club in 1927 , and became a flight instructor . Race against death . In December 1928 Bert Logan , an employee of the Hudson ' s Bay Company was posted to Little Red River , Alberta , on arrival he was unpacking when he suddenly got very ill . His wife , a nurse , realized he had diphtheria , and a desperate effort started to get inoculations to the town before anyone else was seriously infected . Simply getting the word out that help was needed was an adventure in its own , at the time there were no roads in the north , and the nearest telegraph station was miles away over a frozen landscape . The message eventually reached Edmonton , and on January 1 , May was asked if he could deliver the medicine . He left in an Avro Avian with another flying club member , Vic Horner , the next day around noon , and landed on a lake for the night just before 4 p . m . when it was becoming dark . They refueled on the Peace River and continued their flight , arriving in Fort Vermilion at 3 p . m . . A group had just arrived from Little Red River and the drugs were quickly distributed . They had to stop in Peace River on the return flight due to engine damage from the low quality fuels , and didn ' t arrive back in Edmonton until the 7th . By this point his flight had become known across Canada as " the race against death " , and he and the mayor arrived to find a media circus waiting for them in town . The news of this remarkable flight helped May establish a new company , Commercial Airways , to provide air service to Northern Canada . The Company won a government contract for air mail to the Northwest Territories , a service that had been pioneered by Punch Dickins rival Western Canada Airways . Both companies would eventually become part of Canadian Pacific Air Lines . Hunt for the Mad Trapper . In early 1932 May was involved in another manhunt , this time for Albert Johnson , soon known as the " Mad Trapper of Rat River . " While serving a search warrant for illegal trapping on the Rat River , Constable King of the RCMP was shot and wounded by Johnson , sparking off a long chase that became front - page news across the continent . Johnson killed Constable Edger Millen May was again hired to see if he could find Johnson , who had seemingly disappeared . On February 13 , May solved the mystery when he noted a set of footprints leading off from caribou tracks in the middle of the frozen river . Johnson had been following their tracks to hide his own , but had to strike off the path to set up camp at night . Following the trail over the next few days the RCMP rounded a bend on the river on the 17th to find Johnson in the middle of the trail again , unable to dodge for the bank without his snowshoe s on . A firefight broke out during which one of the RCMP officers was seriously wounded and Johnson killed . May arrived just after the action ended , and landed beside the injured officer and flew him 125 miles to a doctor , being credited with saving his life . These actions were later heavily fictionalized in the 1981 Charles Bronson classic Death Hunt . The movie shows May as a fictional RCAF " Captain Tucker " firing wildly at everyone on the ground , including the posse , who fire back and cause him to crash into a mountain . Second World War . With the start of the Second World War , it was decided that Canada would become the major place of training for pilots in the RAF joining from countries in the British Commonwealth . The British Commonwealth Air Training Plan set up airbases across Canada , and May became the commander of the No . 2 Air Observer School in Edmonton , as well as supervisor of all the western schools . While this was going on the United States was also ferrying huge numbers of aircraft to the Soviet Union , flying through Edmonton on their way . A number of these crashed due to mechanical problems , in which case there was no way for an injured pilot to get out of the " back country " when this happened . The idea came up that a team of parachute jumpers should be formed that could be dropped in on the crash sites to stabilize the injuries and start moving the pilots out of the bush . Early efforts were comical but dangerous , but the US trained a number of jumpers at a smokejumper school in Montana , and it was not long before the Para - Rescue team was in service . Several additional Para - Rescue teams were set up during the war , and by the time the war ended the value of these teams was recognized . They were soon re - organized into their own command within the Canadian military , Search and Rescue . For his work in Search and Rescue , May was awarded the Medal of Freedom , with Bronze Palm in 1947 by the USAAF . Death . May was on vacation with his son Denny on June 21 , 1952 . He died from a stroke while hiking to Timpanogos Cave near American Fork , Utah . Legacy . In addition to the DFC and the United States Medal of Freedom , Wop May was awarded the Trans - Canada ( McKee ) Trophy in 1929 and became an Officer in the Order of the British Empire in 1935 . In 1974 , May was declared a National Historic Person , and a plaque to commemorate him was installed in Edmonton in 1978 . May is immortalized in songs by Stompin ' Tom Connors ( " Wop May " ) , The Gumboots ( " Wop May " ) , and John Spearn ( " Roy Brown and Wop May " ) . He was also the subject of a 1979 National Film Board of Canada vignette . On October 6 , 2004 , NASA ' s Mars Exploration Rover Opportunity located a rock on the south slope of the Endurance Crater on Mars . The 1 metre ( 3 . 3 - foot ) rock was given the name " wopmay " after the legendary Canadian bush pilot . Canada has a geologic feature known as the Wopmay Fault Zone , lying to the west of Hudson Bay along the Wopmay river , where the earliest mountains in earth ' s history appeared during the Paleoproterozoic era , approximately two billion years ago . The city of Edmonton , Alberta named the neighbourhood of Mayfield in honour of Wop May .
