The first one has me stumped;I think the second one is Herr Junkers……..so;
1.What’s the maiden name of the first US woman to break the sound barrier ?
2. Surname of the 19th/20th century German who,in 1911,became the first to design and build an all metal aircraft.
1. Jacqueline “Jackie” Cochran`s maiden name was Bessie Lee Pittman.

2. Junkers built the first ‘Ganzmetallflugzeug’, the J1, in 1915, not 1911. Your quiz is wrong 🙂
