Markham hoped to claim both records. On 4 September 1936, she took off from Abingdon, southern England. After a 20-hour flight, her Vega Gull, "The Messenger", suffered fuel starvation due to icing of the fuel tank vents, and she crash-landed at Baleine Cove on Cape Breton Island, Nova Scotia, Canada. She became the first person to make it from England to North America non-stop from east to west and was celebrated as an aviation pioneer.']}}]}]
