I know that you must have enjoyed your visit with Alma. I wished so much that she could have spent more time with us, but we were grateful for the two days. I wonder where she was going these two times. December 30, 1931 was a Wednesday, so it was on December 28 that they saw Alma at the train station.
3. Two weeks ago we saw the “Akron”. Wikipedia says: USS Akron (ZRS-4) was a helium-filled rigid airship of the U.S. Navy, the lead ship of her class, which operated between September 1931 and April 1933. It was the world's first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes, which could be launched and recovered while it was in flight. and: Akron was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. The accident involved the greatest loss of life in any airship crash. So why do we remember only the Hindenberg?
4. On Monday we saw an auto giro. Wikipedia says: An autogyro (from Greek αὐτός and γύρος, "self-turning"), or gyroplane, is a class of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. While similar to a helicopter rotor in appearance, the autogyro's unpowered rotor disc must have air flowing upward across it to make it rotate.
5. Early in the school year the Los Angeles came over the city. I couldn't find anything that fit this.
6. We went to see the “Spirit of Notre Dame” yesterday. A 1931 football movie with Lew Ayres.
7. The key which you will find enclosed is one which Aunt Alma gave us to give to you. I think it is the key to the laboratory. Does this mean that Eva is in South Hadley?
