Please read the following:
Uncle Karl supposes that when the boys take their families to Ocean City for the holidays they’ll fly in Autogiros. Their mother, sitting in the middle of the front seat like Magda in the second, only with her arms on the seat-back behind the men’s shoulders, wouldn’t want the good old days back again, the steaming trains and stuffy long dresses; on the other hand she can do without Autogiros, too if she has to become a grandmother to fly in them.
My question is: What does “if she has to become a grandmother to fly in them” Mean? “Them” should refer to Autogiros. Then it doesn’t make sense to say “she can do without Autogiros, too if she has to become a grandmother to fly in Autogiros”.
Looking forward to hearing from you.
Thank you in advance.
