Were you aware David that some rogue was transmitting they were the Electra floating at least a day later. Authority established it would have sunk very shortly after splash down. Why did she turn back ,when , from memory it was a 20 hr ? flt,and transmit she was on them and had commenced this north south search. It was common to lay off so they knew which way to turn initially. Crossing the Atlantic she missed the originall destination and landed at a French satelite placed for that very reason . I read at one stage there was a primitive battery powered NDB on Howland . In their eagerness it was turned on far to early .Voltage drop caused the range to be considerably reduced yet still providing an ident. Did Nunam rely to much on this.I dispute the Electra would have had 4 hrs fuel on arrival Howland area it was an hour at most. If she had circled the other way as she had originally until ground looping on TO in Hawaii the year before she may have made it, bigger land masses not to miss. BOAC early days crossing the Atlantic with doppler and means to drop a flare,to calclate drift, a bubble for star and sun shots, weather permitting ,planning on London nearly missed Prestwick on more than one occasion
