From Susan Butler's book, page 347:
"Moments after Amelia and Helen took off (from Floyd Bennett Field), a bolt in the hatch cover over their heads worked loose, and the big hatch--big enough to provide access--popped open. Only after the automatic pilot kicked in could Amelia, who was at the controls, help Helen wrestle it closed. At one point, "the wind almost sucked us right out of the cockpit," according to Amelia. It took them two hours before they got it securely into place. When they made their refueling stop in Kanas City precious time was lost while it was wired shut. Later they had to deal with a cabin door that worked loose--all very time-consuming."
Sounds like an exciting trip! (Remember the TIGHAR definition of 'adventure?' Makes me wonder what words AE had for Bo and Lockheed.
