I’m going to guess that you mean commercial airliners on which you ride “go so steep.” Obviously, you feel they go steep, but “steep” is a relative term—one person’s “steep” is another person’s “boring.”
I’LL SHOW YOU “STEEP”
I had the good fortune to get taxpayer-funded pilot training through the U. S. Air Force, which included flying the Northrop T-38 Talon supersonic jet. When it was first introduced, it was the fastest-climbing aircraft in the world and set the world time-to-climb record.
The specific jet they used to set that record had the tail number of 10849. After that record-setting flight, 849 went to the regular training fleet at Webb AFB in Big Spring, Texas, which is where I went to pilot training. The folks at Edwards AFB, where the record was set, painted a list of the various records it had set on the nose, but otherwise, that jet was just a regular member of our fleet at Webb.
Eleven years later, I got to fly 849. Unfortunately, back then there was no such thing as smartphone cameras. If I’d had one, I would have gotten someone to take a pic of that list of records on the nose with me sitting in the cockpit—but, alas!
The records were set in meters, and they ticked off a bunch of them, but the easy one to remember is the climb to 9000 meters because that’s 30,000 feet.
The climb record must be measured from the moment the aircraft first moves on the runway, all the way through takeoff, gear up, and then start climbing. That whole process—from dead-stop on the runway to 30,00 feet—took 62 seconds ... and here’s a photo taken that day, like a scalded angel trying to get back to heaven.
Now that’s what I call a “steep” takeoff.
Airliners do not take off “steep.”
BUT AIRLINERS DON’T HANG AROUND AT LOW ALTITUDE
Jet aircraft are most efficient at high altitudes. The most fuel efficient profile any jet can fly on a cross-country trip would be to climb at its maximum rate all the way to cruising altitude, level off and pull back to cruise power, and stay there until the precise moment the engines can be pulled to idle and descend to a landing.
Due to traffic and passenger comfort, the airliners don’t fly that maximum efficiency profile, but they try to get close.
And that’s why it seems to you that jet airliners climb “relatively steep,” but trust me, they do not fly steep. That T-38 climbed steep!
JUST FOR THE RECORD
A few years later, the F-4 broke the T-38′s record. I haven’t followed the latest, but I clearly recall in 1975 when the F-15 brought the 9000 meter record down to 48.8 seconds.
I just watched a video of an airliner takeoff and saw that it broke ground at about 50 seconds after brake release and they raised the gear at about one minute after brake release.
And so, to simplify this: From brake release, the F-15 can be at 30,000 in the time that a typical airliner is just raising its nose on the runway. Forty. Eight. Point. Eight. Seconds.
The F-15 has a thrust-to-weight ratio of greater than one, which means it can accelerate going perfectly vertical, like a ballistic rocket.
Now that, my friends, is the ultimate in “steep.”

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.
As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.
The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.
Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.
If you asked a few random people to name a situation that wouldn’t be protected under the First Amendment’s “freedom of speech” clause, there’s a pretty good chance at least one of them would mention the example of someone shouting “Fire!” in a crowded theater (when there’s no fire). Over the last century, the scene has been used far and wide to illustrate that if your “free speech” harms people, you can still end up in the defendant’s chair. But, as is so often the case when it comes to interpreting the law, it’s really not that simple.
When people first started discussing human fire alarms at packed gatherings, it was less about constitutional debate and more about societal menace. During the late 18th and early 19th centuries, there were dozens of tragedies [PDF]—mainly in the U.S., but also abroad—where false shouts of “Fire!” provoked panic that resulted in multiple innocent, and avoidable, deaths. In 1913, for example, residents of Calumet, Michigan, held a Christmas party for the children of copper miners on strike. Hundreds of people gathered on the second floor of Italian Hall, and when an unidentified perpetrator (possibly motivated by anti-union sentiments) yelled “Fire!” they all rushed to the stairs. The stampede claimed 73 victims, most of whom were children.
The fear of fire wasn’t unfounded. Since not all buildings had sprinkler systems, neon exit signs, and capacity limits, plenty of fatal blazes occurred. More than 600 people died in Chicago’s Iroquois Theater fire in 1903, even though (ironically) that building was actually thought to be fireproof.
In short, shouting “Fire!” in a crowded theater was an idea firmly entrenched in the public consciousness by the time judges co-opted the phrase for legal arguments on First Amendment rights.
Discussing Fire in a Crowded Courtroom
The axiom became popular in legal spheres after Supreme Court Justice Oliver Wendell Holmes Jr. mentioned it during Schenck v. United States in 1919, but he wasn’t the first person to use it in court. As Carlton F.W. Lawson pointed out in a 2015 article in the William & Mary Bill of Rights Journal, U.S. attorney Edwin Wertz had uttered a lengthier version of it the previous year while prosecuting activist Eugene Debs. In fact, since Holmes ruled on Debs’s appeal the very week after the Schenck case, he may have even gotten the idea from Wertz.
Each case involved a violation of the Espionage Act of 1917, which essentially made it punishable to do anything that interfered with U.S. military operations—including speaking out against the draft. Debs, a pacifist who opposed World War I, was under fire for a speech he had given in Ohio; and Charles T. Schenck, the U.S. Socialist Party’s general secretary, landed in front of the Supreme Court for passing out pamphlets that encouraged men to refuse the draft.
Both defendants were convicted, and Holmes justified his ruling on the Schenck case with the explanation that “the most stringent protection of free speech would not protect a man in falsely shouting ‘fire’ in a theater and causing a panic.” But while his analogy struck an emotional chord, it really had nothing to do with constitutional law.
“The ‘crowded theater’ statement in Schenck never amounted to any kind of binding standard or doctrine,” Nashwa Gewaily, a media and First Amendment lawyer, tells Mental Floss. “It was basically a bit of emotionally charged extra flair from Justice Holmes, outside the official legal determination of that case; a powerful image that endured outside its context ... It was not a high point in American jurisprudence.”
“Revengeance” Is Fine
What Holmes said after it, however, did become a standard for future free speech arguments. “The question in every case,” he said, “is whether the words are used in such circumstances and are of such a nature as to create a clear and present danger that they will bring about the substantive evils that Congress has a right to prevent.”
For the next 50 years, clear and present danger was the accepted—and slightly vague—metric for discerning if spoken or printed material was protected speech. Then, in 1969, the Supreme Court replaced it with something clearer. The case, Brandenburg v. Ohio, concerned a Ku Klux Klan leader named Clarence Brandenburg who had broken Ohio’s law against advocating “crime, sabotage, or unlawful methods of terrorism” for political purposes. (In his offending speech, he had mentioned the possibility of “revengeance” [sic] if the federal government didn’t stop “[suppressing] the white, Caucasian race.”)
Brandenburg appealed his guilty verdict all the way up to the Supreme Court, which overturned the ruling on the grounds that his threats were too ambiguous to “[incite] or [produce] imminent lawless action.” In order for something to qualify as imminent lawless action, it must: expressly advocate violence, advocate immediate violence, and relate to violence likely to occur.
As Gewaily explains, judges interpret this standard “far more narrowly than many would presume.” While individual institutions may condemn hate speech, for example, it’s technically protected under the law unless there’s “immediate violence” involved.
When Free Speech Is the Least of Your Worries
So, does falsely shouting “Fire!” in a crowded theater fall outside the conditions of imminent lawless action, and therefore fall under First Amendment protection? The short answer is that it depends on the circumstances. But here’s the long answer: If you get arrested for doing that, the charges brought against you might make the question of free speech totally irrelevant.
“The falsely shouted warning, while technically speech, could potentially violate a state's criminal laws against disturbing the peace or disorderly conduct, whether or not it provokes a stampede, for instance,” Gewaily says. And if there is a stampede in which somebody dies, you could be charged with involuntary manslaughter. In other words, there’s no law that explicitly prohibits you from crying “Fire” in a theater. It’s the other laws you’d have to worry about.
Shouting “Bomb!” or “Gun!” in public would put you in a similar situation. In May 2018, for example, officials had to evacuate part of Daytona Beach International Airport after a man ran naked through the building screaming about a bomb in the women’s bathroom. There was no bomb, but he was charged with “false report of a bomb,” “criminal mischief,” and “exposure of sexual organs,” among other things. In that case, no self-respecting lawyer would advise him to claim his actions were protected by the First Amendment.
That said, there’s good news for anyone whose panicked cry is an honest mistake. “Someone who shouts a warning in genuine error, with an intent to galvanize movement to safety, would not be properly punished for that speech,” Gewaily says.
And if Oliver Wendell Holmes Jr. has taught us anything, it’s that not every word a Supreme Court Justice says automatically counts as constitutional doctrine.
