Nope. Think earlier.
Unfortunately, while I know there were many earlier flying boats, I couldn’t name a single one (well, except for the Dornier SuperWal, which I’d not expect to be flying in the US, let alone this long after it was introduced.) without either checking Google, or Wikipedia. It was no more than a stab in the dark.
Let’s add a few more planey questions…
-
This little-known predecessor to the SR-71 Blackbird looked almost identical, but wasn’t, and even came in a combat version.
-
What was the Navy’s A-4D more commonly known as?
-
What was the name of the plane that first bore Charles Lindbergh across the Atlantic?
The Spirit of St. Louis.
-
Warthog?
-
Bet this is a trick question…IIRC Lindbergh first flew across the Atlantic on a plane piloted by a couple of French aviators, a year or so before his solo in The Spirit of St Louis. Wish I could remember the name of that French plane…
edited for spelling
Boxcar as one word? Boxcars? Dang, I was sure it was Box Car. I hope someone answers it correctly soon, because now I cannot look it up. 
Rocks Songs & American History
-
The WeatherUnderground took its name from a line in this 1960’s song.
-
The killing of 4 Kent State students inspired this song.
-
To whom was Graham Nash referring to in the line “so your brother’s bound & gagged and they’ve chained him to a chair”
-
What was wrong with U2’s reference to Dr. Martin Luther King in Pride in the Name of Love?
-
These two Senators from opposite sides of the aisle did a duet of a popular 1960’s song.
-
Crosby, Stills, Nash & Young - Ohio
-
I think the lyric is “Early morning - April 4. Shots ring out in the Memphis Sky.” But King was killed in the evening.
-
Incorrect. Warthog is the A-10 (which is an Air Force-only aircraft).
-
Are you sure that wasn’t the English Channel? I was under the impression that Lindbergh was the first to fly across the Atlantic - *Spirit of St. Louis * was the answer I was looking for.
correct
Hmmm. Who said it was a flying boat?
Here are my two guesses:
- YF-21
- Intruder
Who said it? Bonus points for context.
- “One war at a time.”
- “This generation has a rendezvous with destiny.”
- “The tree of Liberty is plant of rapid growth.”
- “These are the times that try men’s souls.”
- “Who is that awful man?”
I’ll give it to you. It was Bock’s Car.
Well, I’ll be. I’m sure I must have read that, but for years I’ve thought it was Box Car.
Thanks. 
- Thomas Paine? In Common Sense?
Paine, yes, but in a later work. The Winter Soldiers, mebbe? As for Bock’s Car, you’re welcome.
- FDR, during the Yalta talks with Churchill and Stalin (ie. no, we’re not opening a second front in Europe)
- Walter Cronkite.
- I know Jefferson liked the phrase “tree of liberty”, so let’s go with him.
- Jackie Kennedy, referring to Kruschev.
Yes, those are all WAGs.
- Sen. Everett McKinley Dirksen (R-Ill) and Robert Francis Kennedy (D-NY) hilariously recorded Wild Thing, mocking their own rhetorical flourishes in the process.
The RS-71 bore designation while under development, until the President (Lyndon B. Johnson, IIRC) announced its adoption to the nation as the SR-71. Like Cunard when George V misunderstood what they proposed to call the new ocean liner (intended to be Victoria, they went with his misprision and named it the Queen Mary instead), the designers gulped and revised the designation to what the President had said.
Er… wasn’t the SR-71 not announced to the public until awhile after it entered service? I thought it was kept secret (to keep it secret from the Soviets).
Actually, it’s important to remember that Lindbergh was the first man to solo across the Atlantic. There had been several prior air crossings - but all with multiple pilots and crew.
It may well not be a flying boat, but for a number of reasons, it seems logical to me to guess that it may have been. First off, flying boats have several advantages when dealing with small island destinations - there’s no need to clear land, improve it, and then build and maintain an airstrip. Secondly, for a number of reasons, there were a lot more flying boats than many people realize during the early era of flight, so by specifying it was an antique aircraft, I figure there’s at least some reason to seriously consider a flying boat just for that consideration.
Of course, I may have been using logic to jump into a quagmire - I’ve done it before, after all.
