How fast were the planes going when they hit the towers? (2023)

How fast was the airplane going when it took off?

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph).

Researchers trying to explain why the World Trade Center's south tower fell first, though struck second, are focusing on new calculations showing that the passenger jet that hit the south tower had been flying as fast as 586 miles an hour, about 100 miles an hour faster than the other hijacked plane.

The plane crashed in an open field next to a wooded area in Stonycreek Township, Somerset County, Pennsylvania at 10:03:11 am. The nearest town is Shanksville. Flight 93 struck the ground at a 40 degree angle almost upside down, hitting right wing and nose first, at a speed of between 563-580 miles per hour.

The buildings collapsed within ten seconds, hitting bottom with an estimated speed of 200 km/h (Getty Images). The egg-crate construction made a redundant structure (i.e., if one or two columns were lost, the loads would shift into adjacent columns and the building would remain standing).

Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.

The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3--that's more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71's design made this possible.

Thirty-four minutes later, at 9:37 a.m., American Airlines Flight 77, crashes into the Pentagon collapsing part of the building. Then at 9:59 a.m., the burning WTC South Tower collapses. Four minutes later, at 10:03 a.m., United Airlines Flight 93, crashes in a field near Shanksville, Pennsylvania.

The hijacked Flight 11 was crashed into floors 93 to 99 of the North Tower (1 WTC) at 8:46 a.m. The hijacked Flight 175 struck floors 77 to 85 of the South Tower (2 WTC) 17 minutes later at 9:03 a.m. When the towers were struck, between 16,400 and 18,000 people were in the WTC complex.

Did any people survive Flight 93?

Primarily airplane wreckage, some personal effects, and a very small amount of unidentified human remains were found.

The work took ten months and involved employees from dozens of City, State and federal agencies and the tireless efforts of responders, laborers, contractors, volunteers, and community organizations.

Only 16 individuals who were inside the collapsing North Tower survived and were rescued, and they were all trying to evacuate via stairwell B located in the center of the building. 4 people who were in the concourse area between the Twin Towers survived and either saved themselves or were rescued.

Of the 2,977 victims killed in the September 11 attacks, 421 were emergency workers in New York City who responded to the World Trade Center. This included: 343 firefighters (including a chaplain and two paramedics) of the New York City Fire Department (FDNY);

Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal. Astronauts endure around 3G on lift-off, one G of which is Earth's own pull.

The current holder of the Outright World Land Speed Record is ThrustSSC driven by Andy Green, a twin turbofan jet-powered car which achieved 763.035 mph - 1227.985 km/h - over one mile in October 1997. This is the first supersonic record as it exceeded the sound barrier at Mach 1.016.

PZL M-15 Belphegor.

The slowest powered plane ever flown (even if it was human powered) was the MacCready Gossamer Albatross. And it was very slow – topping out at 18mph.

Its minimum takeoff speed is about 20 mph and its cruising speed is around 45 mph.

What floor did the plane hit Tower 1?

8:46:40: Flight 11 crashes at roughly 466 mph (750 km/h, 208 m/s or 405 knots) into the north face of the North Tower (1 WTC) of the World Trade Center, between floors 93 and 99. The aircraft enters the tower intact.

Reportedly financed by the al Qaeda terrorist organization of Saudi fugitive Osama bin Laden, they were allegedly acting in retaliation for America's support of Israel, its involvement in the Persian Gulf War and its continued military presence in the Middle East.

During the emergency response, there was minimal communication between the NYPD and the New York City Fire Department (FDNY), and overwhelmed 9-1-1 dispatchers did not pass along information to FDNY commanders on-scene. At 9:59 a.m., the South Tower collapsed, around 56 minutes after being struck.

Search and rescue efforts

On the day following the attacks, eleven people were rescued from the rubble, including six firefighters and three police officers.

The 1918 Flu Pandemic: 675,000

The 1918 flu claimed an unfathomable 50 to 100 million victims worldwide, including an estimated 675,000 Americans. Wrongfully labeled the “Spanish flu,” the first confirmed case of this virulent strain of influenza was actually a U.S. Army cook stationed in Kansas in March of 1918.

Each of the Twin Towers had 110 floors. Each tower's footprint and floors were approximately an acre in size. On windy days, each tower could sway up to almost 12 inches side to side. There were 43,600 windows in the Twin Towers, equating to more than 600,000 square feet of glass.

The explosion ripped through the 78th floor sky lobby. Of the people there, the only survivors were those standing in alcoves, or farthest from where the plane hit. "There were over 200 people on the 78th floor," Crown said, "and I was fortunate to be in one square foot where I was able to survive the impact."

The demolition was ordered by the Supreme Court after the court found their construction on the Emerald Court society premises in violation of norms. The buildings will be demolished by the company at its own expense under the guidance of the Noida Authority.

It is unknown how the hijackers gained access to the cockpit; FAA rules at the time required that the doors remain closed and locked during flight. Ong said she thought that the hijackers had "jammed their way" in.

How many planes crashed on 911?

On September 11, 2001, 2,977 people were killed in the deadliest terrorist attacks in American history. The moment shocked the nation. Two planes, hijacked by Islamic jihadists vowing death to all Americans, plowed into both towers at the World Trade Center in New York.

The hijackers deliberately crashed the plane into the Pentagon in Arlington County, Virginia, near Washington, D.C., killing all 64 aboard (including six crew and themselves) and another 125 in the building.

But for many Americans who didn't see or feel that moment on 9/11, it was like Flight 93 disappeared — something that fueled conspiracy theories for years. Instead, the plane's remnants were battered and buried deep in a reclaimed strip mine's backfill.

It was a big deal when we did find it and I believe it was slightly over 25 feet into the crater. In the case of the flight data and voice recorders, they were taken out to Seattle because they were damaged to the point where they had to go back to the manufacturer.

At age 20, Deora Frances Bodley of San Diego, California was the youngest person aboard Flight 93.

Tim Lambert's family owned part of the tree-filled land where Flight 93 crashed on Sept. 11, 2001. Tim Lambert, weary from a long day of reporting on Sept.

According to the FBI, thirty-seven phone calls were placed from on board Flight 93 between 9:28 when the plane was hijacked until the time of the crash at 10:03. Thirty-five of these calls were made on the Airfones located on the back of the seats in the last nine rows of the plane.

Bram, Orr, and Rapaport present a detailed account of the costs of the World Trade Center attack. Using data through June 2002—the month in which the recovery process at the tradecenter site ended—they estimate that earnings losses, property damage, and cleanup costs total between $33 billion and $36 billion.

The September 11 attacks in 2001 were followed by initial shocks causing global stock markets to drop sharply. The attacks themselves resulted in approximately $40 billion in insurance losses, making it one of the largest insured events ever.

In the five months following the attacks, dust from the pulverized buildings continued to fill the air of the World Trade Center site. Increasing numbers of New York residents are reporting symptoms of Ground Zero respiratory illnesses.

Who was the last person pulled out of the Twin Towers alive?

Lessons from the Last Survivor

Join us virtually to listen to Genelle Guzman-McMillan—the last survivor pulled from the 9/11 wreckage—recount her courageous story about surviving the fall of the Twin Towers and her wait for rescue. Her story is one of strength and finding one's faith even in the darkest of moments.

But just two people were rescued from underneath the ruin: Jimeno and his sergeant that day, John McLoughlin. Jimeno and McLoughlin's story is an incredible tale of survival — one featured in a 2006 Oliver Stone movie.

343 is a well known number in the fire service as it represents the number of New York Fire Department members that perished in the terrorist attacks on 09-11-2001. They made the ultimate sacrifice along with many police officers and medical personnel that day after running headfirst into the Twin Towers.

Thus, firefighters should be able to sleep for at least six to eight hours when they're on the job. On their days off, they can sleep for 10 or 12 hours or longer if they wanted to. Again though, we must stress that a firefighter is always on call, so their sleep can be interrupted even on a day off.

Jonathan Briley

It was adapted into a documentary film by the same name. The article gave the possible identity of the falling man as Jonathan Briley, a 33-year-old sound engineer who worked at Windows on the World. Briley had asthma and would have known he was in danger when smoke began to pour into the restaurant.

How Fast Does a 747 Go To Take Off? A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.

During this time, planes were flying at speeds of around 100 mph, had to stop to refuel often, and could only travel by day. Flying in the 1920s was also an uncomfortable experience for passengers because it was loud and cold, as planes were made of uninsulated sheets of metal that shook loudly in the wind.

What speed does a Boeing 747 land at? A 747 'Jumbo Jet' would typically land at a speed of about 145kts-150kts (166mph-172mph), depending on the landing flap setting selected.

When the war began, aircraft could barely reach speeds of 50mph - this was increased to 150mph by war's end. As with any war, World War 1 pushed the limited of the technology of the period, providing the canvas for new engines with corresponding airframes developed to certain military specifications.

What is the slowest speed a jet can fly?

Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

A normal landing speed is 160–165 kts (at 600,000 to 650,000 lbs). When completely empty, with a light fuel load (as in a short Mx ferry or repositioning flight after offloading), we could get as slow as 130 kts on landing (below 400,000 lbs).

A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!

Nervous fliers of the Sixties and Seventies also had to the contend with the fact that flying was - statistically speaking - up to 77 times more dangerous. The deadliest year in aviation history? That was 1972, when 72 accidents resulted in 2,373 fatalities.

In the 50s, a flight from Chicago to Phoenix could cost $138 round-trip -- that's $1,168 when adjusted for today's inflation. A one-way to Rome would set you back more than $3,000 in today's dollars. Lobster counted as airplane food.

The fastest aircraft to see any combat in WWII was the Messerschmitt Me 163, which set an airspeed record of 702 mph in 1944 (although this record was not recognized by the Fédération Aéronautique Internationale due to its secrecy during the war).

Planes can fly at 1000 mph. Excellent examples of planes that could fly at 1000 mph include: Lockheed SR71 Blackbird (2193.2mph)

When a pilot uses the phrase “heavy,” he is reminding ATC that his aircraft is large and requires more separation between it and the aircraft following.

Depending on numerous factors, the average price for a pre-owned BOEING 747-400 is $20,000,000.00. A $10,000,000.00 loan over 120 months including $41666.67 per month in interest equates to a $501,437.15 per-period payment.

The tanks were capable of, at best, 6 km/h (4 mph), matching the speed of marching infantry with whom they were to be integrated to aid in the destruction of enemy machine guns. In practice, their speed on the broken ground could be as little as 1 mph.

What plane was faster than its bullets?

Once the legend of the skies, the X-15 flew faster than a rifle bullet and lofted its pilots to the edge of space 60 miles up. Washington: They swept the dirt from its path as the old rocket plane was rolled out of the Smithsonian's National Air and Space Museum on Tuesday night.
