IIRC there was a block out for a full week regarding flight entrance records during the said period, hmmm!!!
Nothing to see???
Your recollection is excellent. The National Archives record of foreign arrivals to HI is complete...except for one week. The week that includes Aug 4, 1961, is missing. It was stolen. The crucial question is, who arrived in HI that week from a foreign country whose identity, were it to become known, would devastate Obama’s nativity tale?
The narrative that makes the most sense is granny Dunham returning from Canada. That fits with Obama’s statement that he was born in the third week of July. Granny stayed through the birth and for several days after, and then returned to HI. It all fits.
