NOTES:

  • Due to weather delays, this was the longest migration in the project's 7-year history.

  • They were grounded by unflyable weather for as many as 10 days in a row (a NEW record, set in Cumberland County, Tennessee).
  • For the first time ever, the migration ran from one calendar year into the next; the team took a break (in December) to go home to visit families.
  • Crane #733 went missing on the Nov. 23 flight and wasn't found until 6 days later.
  • The cranes and planes turned back on their Dec. 17 attempt to cross the highest mountain ridge of the migration course.
