So just to clear the air (and I guess my massive confusion) Harry never slept with Sandra, correct? I gotta say I need to read his memoir at this point as he is so intriguing to me, as well as masters of the air book, but like you said it’s a “blink and miss it” thing. I didn’t interpret it as anything more than having a few friendly conversations. It was more about emotional infidelity to me than physical, but given the circumstances and that exact heartbreaking point in time for Harry I can’t find it in me to blame either of them.

for me, ig i'm coming at my position from a place of bias. i'd read crosby's "a wing and a prayer" sometime in either 2021 or 2022 (those years blend together tbh), so i've had a lot of time to think about those 2 and their relationship and i lean towards "yeah, it likely happened" (this is a long response btw bc i'm quoting from the memoir):

crosby introduces his new friend, alexandra "landra" wingate (aka sandra westgate), in the chapter "learning about americans from the british" (this chapter was basically what we see in episode 6). moving on from this tho–

in the chapter "with landra in london", he expands on their growing relationship and the reader learns more about landra (she is genuinely Such an interesting person, and probably a spy). crosby writes about her with such admiration, regularly bringing up how smart she is. also, she's a captain!

this chapter's pretty important in how i formed my opinion on the matter. i understand the argument that the closeness of their relationship was intentionally left vague, but this chapter reads in a way that makes it feel Heavily implied despite not saying a lot (especially alongside crosby's emphasis on his wife jean being "four thousand miles away", as well as his own loneliness and despair wrt to all the missing and dead). there are some standout lines here:

-"I had Jean at home and Landra in England." (not a red flag, but it's a flag) -"I started seeing Landra every time I could." (cool) -"All I knew was that [Landra] was making my life much more endurable." (also cool) -"I did not tell Jean about Landra." (the last sentence of the chapter. it gave me pause and almost instantly reshaped the way i viewed that whole chapter)

the next chapter, "r&r with jean", crosby recalls how much the war took a toll on both him and his relationships. for a time, jean wrote more letters to croby than the other way around ("I began to skip writing to her."). i assume crosby must've been radiating Exceptionally negative energy bc he gets told this: "Croz, we can't stand to have you around. We want you back, but we want you to go home for a while." (i found the phrasing here really funny tbh. your vibes Suck! just Get Out of here!!)

so, crosby contemplates seeing jean again, wondering how both of them may have changed. he also brings up landra, for Some Reason: "What would I think of her? Protected in the States as she was, how would she compare to Landra? Now that I had grown so much, had such experiences, how would Jean and I fit together?"

the rest of the chapter Is about meeting and catching up with jean, however, and you can tell that he loves her a Ton. it's very sweetly written (he also basically ends the chapter saying "btw, we conceived our first child ;) ")

the final chapter about landra is "london junket" which begins with "When I returned from the United States and my idyll with Jean, I knew I had to do something about Landra." i think that sentence alone is pretty damning. if landra was just a friend, why would you be anxious about calling a friendship off? is it a guilt thing?

the context here is that crosby feels Far less lonely and depressed. he's met up with jean, life in london is finally "a delight". i found that important bc it gives me the impression that crosby desperately wanted companionship (possibly of two kinds), and he found that in landra– a friend and a maybe a [REDACTED]. now that he's having a great time with his friends in the 100th And he's met up with his wife, that itch's been scratched (that's just my opinion tho). bc of that, he decides to say goodbye to landra. they have this exchange:

"When a month passed after you were to return, and you did not phone me," she said, "I suspected that it was over. You found things good with Jean?" I told her about R&R in the U.S. I told her more about Jean. I told her about Stephen Patrick, Jeffrey Allen, or Evalyn. "When I realized you were gone," she said, "I no longer said no to a nice American at my office. I have been with him several times. I like him." (interesting) "I’m glad." (also interesting) "He is not married, He is not so dashing as you, but we have good times together." Me "dashing"? That was not my self-image. So much for Landra."

all put together (and with over 2 years to think about it), i Really kinda saw That Scene coming. but, like i said, i had that bias. and since i'd had a good amount of time to think about them, i came out the other end still excited to see them on screen. i found (and still find) landra a fascinating woman who must've had an exciting life (crosby's okay too ig lol). i also see them as a couple of imperfect, even selfish, 20somethings (speaking as an imperfect and selfish 20something). not to be corny, but "it takes 2 to tango". landra is Very intelligent, and crosby recounts how that aspect of hers left him in awe. she'd've 100% known the guy was married. and if signs point to her having had sex with the man, then she either made peace with it or simply didn't care (a lot of women are like that). plus, they're real people and real people contain multitudes idk. maybe some wife somewhere across the atlantic is hard to care about if you've never met her and never will. maybe it's hard to consider your wife's feelings in the midst of your own misery. a female character doesn't have to be wholesome and pure to be considered well-written. that certainly doesn't apply to most male characters. like you said, no one is perfect!

maybe, crosby left it vague out of respect to his wife. maybe it's vague bc nothing happened anyway (funny way to write it tho). maybe the wingate family wanted to avoid association with MotA bc it Literally didn't happen. or maybe they know it happened, but want to keep her name clean out of respect (who wants one brief relationship that happened 80 yrs ago to define you/your loved one decades later? that's 100% understandable). whichever the case, even crosby's kids are in a 50/50 split. i still lean towards "it happened", but it doesn't make me dislike either of them. they're flawed and i can respect that more than the show portraying either as picture perfect.

NONE of this is to say that i'm cool with cheating (or giving a "world war cheating pass", so to speak). while i find it realistic, it still wouldn't have been fair to jean, whether she knew about it or not (being a woman in the 1940s wasn't easy by any stretch). this Also isn't to dismiss anyone else's opinion on the matter, bc cheating on your partner is still a shitty thing to do. this whole spiel of mine is bc i like to share my opinions and i'm allergic to being concise. i write like i talk and on all levels except physical, anon, i'm giving you a long-winded rant over coffee and croissants lol

thanks for the ask!
