14th Street Bridge, the Air Florida Crash, and Subway Disaster
The Air Florida crash on Wednesday, January 13, 1982 is very well covered, from an aviation
standpoint.
There was a major snowstorm that was covering the Washington, D.C. area with considerable
accumulation, and there was an early release of federal employees, and heavy strain on the
region's transportation system.
The plane had taken off from nearby Washington National Airport, and due to wing icing and
pilot error, the aircraft lost altitude and crashed into the 14th Street Bridge and the Potomac River
less than a mile from the airport. There were only 5 survivors out of 79 people on board. The
plane was a Boeing 737 two-engine jet airliner that was Air Florida Flight 90. The aircraft
descended nose-high and tail-low, and at 4:01 PM, the tail struck the deck and parapet.栏杆, 低
墙, 扶手, 胸墙 of the Rochambeau Bridge (the northbound span), struck seven vehicles, killed
4 motorists and injured 4 motorists, and went into the frozen river between the Rochambeau
Bridge and the express span (they are a couple hundred yards apart). The aircraft shattered the
surface ice, and broke into multiple large pieces which quickly sank into the river. There were a
total of 78 fatalities. Traffic was already stopped in a traffic jam, due to the storm. Between the
effects of the storm, and the rescue efforts around the 14th Street bridges, the 12-lane complex
ceased to function, and closed to traffic. The George Washington Parkway, which parallels the
Potomac River in Virginia, also closed near the crash site.
A rapid rail transit 运输, 运输线 accident occurred about one half hour after the air crash. At
4:30 PM. This occurred on the Blue/Orange Line, and resulted in the both lines being shut down.
At that time, the Blue Line ran from National Airport Station in Arlington to Addison Road
Station in Maryland, and the Orange Line ran from Ballston Station in Arlington to New
Carrolton Station in Maryland. The derailment occurred on the section where the two lines share
the same cross-town subway route, and the wrecked subway car blocked both tracks. The other
(then) open line, the Red Line, was not affected.
So in a one hour period, the D.C. area lost the use of its (at that time) busiest airport, busiest
expressway, and busiest subway line. The (by far) widest/busiest bridge from D.C. to Virginia
closed, and the one rapid rail transit line from D.C. to Virginia closed. This was a true area-wide
transportation disaster, a major chunk of the air, highway, and rail system closed.
The subway accident had no connection whatsoever with the air crash. The snowstorm put
increased passenger loads on Metro, but that is a casual factor at best for causing the derailment.
During the period of closures of the subway tunnel and the 14th Street Bridge, there were major
traffic and transit jams. Ten-mile-long peak period backups were common on some major
thoroughfares. Some trips that ordinarily took 40 minutes by auto or transit, took 3 to 4 hours,
1
and peak periods stretched far beyond normal peak period times. The snowstorm on the day of
the disasters dropped an average of 6 inches of snow, and many places got 4 more inches by the
next morning. Snow removal was complicated by sub-freezing temperatures and generally bad
traffic conditions.
The Rochambeau Bridge was later renamed the Arland D. Williams, Jr. Memorial Bridge, after
the heroic Flight 90 passenger who perished while saving others from the icy waters.
"He was about 50 years old, one of half a dozen survivors clinging to twisted wreckage bobbing
in the icy Potomac when the first helicopter arrived. To the copter's two-man Park Police crew he
seemed the most alert. Life vests were dropped, then a flotation ball. The man passed them to the
others. On two occasions, the crew recalled last night, he handed away a life line from the
hovering machine that could have dragged him to safety. The helicopter crew - who rescued five
people, the only persons who survived from the jetliner - lifted a woman to the riverbank, then
dragged three more persons across the ice to safety. Then the life line saved a woman who was
trying to swim away from the sinking wreckage, and the helicopter pilot, Donald W. Usher,
returned to the scene, but the man was gone," from "A Hero - Passenger Aids Others, Then Dies",
The Washington Post, January 14, 1982.
January 13, 1982 brought one of the worst blizzards in history to Washington, D.C. Businesses
closed early, schools closed their doors, and even Congress recessed early. Washington's National
Airport had been closed all morning, but re-opened by 12:00 pm. Sitting at gate B12 was Boeing
737-222B, in command of the aircraft, were Capt. Larry Wheaton and First Officer Roger Pettit,
both relatively young pilots enjoying their new jobs at Air Florida. The flight was scheduled to
depart at 2:15, but both men knew that time would come and go.
Just before 1:40 pm, the airport was closed so that crews could plow the field's one instrument
runway, 18/36. It was scheduled to re-open at 2:30. Despite the delay, Air Florida elected to
begin the boarding process, and all passengers were on board by 2:30. Meanwhile, Capt.
Wheaton had ordered de-icing to begin. The tower told him to expect a further delay, and he
requested that de-icing be halted. 'Palm 90' was number 11 for departure when the airport
reopened.
At 3:00, Wheaton instructed de-icing to continue, and the job was done by 3:10. Ground
personnel reported only a "light dusting" of snow on the wings. At 3:23 pm, 'Palm 90' was
cleared to push from the gate and the towing 牵引 equipment was attached. Due to the deep
accumulations of snow, however, the TUG was unsuccesful in its attempts to push the aircraft,
and contrary to company policy, Wheaton elected to use the reverse thrust to back the airplane
out of the gate. The reversers were engaged for a minute and a half, but only succeeded in
sucking large amounts of storm debris into the engines. Finally, cooler heads prevailed, and a
TUG with chains attached was called in. The aircraft was successfully pushed back.
'Palm 90' then proceeded to taxi into position behind a New York Air DC-9, the last of sixteen
aircraft in line for takeoff. With a light snow still falling, Wheaton decided to use the hot exhaust
2
from the preceeding DC-9's engines to melt the snow off the wings, which in the end only had the
effect of pushing it to the trailing portion of the wing to refreeze. The aircraft's anti-ice system
was unable to de-ice this portion of the wing, not that it made any difference.
While running through the takeoff checklist, the following conversation took place:
CAM-2: Air conditioning and pressurization?
CAM-1: Set.
CAM-2: Engine anti-ice?
CAM-1: Off.
When the Cockpit 驾驶员座舱 Voice Recorder tape was played back after recovery, there was
much disagreement about Capt. Wheaton's response to "anti-ice." Many of the investigators could
not accept the fact that, despite the freezing 20 degree temperatures and 25+ inches of snow on
the ground, Wheaton said "off." The tapes were taken to the FBI Labs in Washington for analasys,
and it was concluded that the word was, in fact, "off." Apparently, despite the weather, the crew
had forgotten to activate the anti-ice systems.
At 3:59 pm, 'Palm 90' was cleared for takeoff with the remark "no delay on departure, if you will,
traffic's two and a half out for the runway," added a few seconds later by ATC. Pettit advanced
the throttles, and quickly responded "real cold, real cold," implying that the engines reached the
takeoff EPR of 2.04 before the throttles had been fully advanced. Throughout the entire takeoff
roll, the First Officer tried to inform the Captain that something wasn't right, but it was in vain.
Wheaton was sure everything was in order:
15:59:51 CAM-1 It's spooled. Real cold, real cold.
15:59:58 CAM-2 God, look at that thing. That don't seem right, does it? Uh, that's not right.
16:00:09 CAM-1 Yes it is, there's eighty.
16:00:10 CAM-2 Naw, I don't think that's right. Ah, maybe it is.
16:00:21 CAM-1 Hundred and twenty.
16:00:23 CAM-2 I don't know.
16:00:31 CAM-1 Vee-one. Easy, vee-two.

At rotation speed, the aircraft pitched up sharply, causing
Wheaton to reply "easy." It was a known fact that ice
buildup on the wings of a 737 can cause a tendancy to
pitch up. Pettit's correction of the nose-up attitude,
however, failed to resolve the problem and the
stickshaker immediately began to sound. Wheaton called
"Forward, forward, easy. We only want 500," refering to
the altitude at which the airplane had to be to make the 40
degree turn to the left around the Washington Monument
and the restricted airspace over the Capitol.
"Come on. Forward, forward. Just barely climb," exclaimed Wheaton as the aircraft continued to
stall. Moments later the aircraft was no longer climbing, but falling back to earth.

"Stalling, we're falling."
"Larry, we're going down Larry."
"I know it."
These are the last words spoken from the cockpit of 'Palm 90.' The aircraft came down directly on
top of the 14th Street Bridge, which spans the Potomac River and is a major route from the
Virginia suburbs into the city. Four automobiles were crushed, resulting in five deaths on the
ground. The aircraft then impacted the icy water and quickly sank to the bottom. In the hours
after the crash, only four passengers and a Flight Attendant would be pulled alive from the icy
water.
The investigation of the crash concluded that the combination of the crew's use of thrust reverse
on the ground, and their failure to active the engine anti-ice system, caused the crash. By failing
to activate the engine anti-ice, the large amouts of snow and ice that were sucked into the engines
during reverse thrust use was allowed to remain there, unchallenged. The ice buildup on the
compressor inlet pressure probe, the probe which measures engine power, can cause false
readings, as was the case here. The indications in the cockpit showed an Engine Pressure Ratio of
2.04, while the power plants were in reality only producing 1.70 EPR, or about 70% of available
power. The combination of the ice covered wings and low power caused an immediate stall 停止,
迟延 on takeoff that resulted in 74 lives lost.

Everyman (after 1485)
Everyman is the best surviving example of the
type of Medieval drama known as the morality
play. Moralities evolved side by side with the
mystery plays, although they were composed
individually and not in cycles. The moralities
employed allegory.寓言 to dramatize the moral
struggle Christianity envisions 想象, 预想
universal in every individual.
Everyman, a short play of some 900 lines,
portrays a complacent.自满的, 得意的

Everyman who is informed by Death of his
approaching end. The play shows the hero's progression from despair and fear of death
to a "Christian resignation 顺从 that is the prelude to redemption."1 First, Everyman is
deserted by his false friends: his casual companions, his kin, and his wealth. He falls
back on 求助于 his Good Deeds, his Strength, his Beauty, his Intelligence, and his
Knowledge. These assist him in making his Book of Accounts, but at the end, when he
must go to the grave, all desert him save his Good Deeds alone. The play makes its
grim.严酷的 point that we can take with us from this world nothing that we have
received, only what we have given.
The play was written near the end of the fifteenth century. It is probably a translation
from a Flemish play, Elckerlijk (or Elckerlyc) first printed in 1495, although there is a
possibility that Everyman is the original, the Flemish play the translation. There are four
surviving versions of Everyman, two of them fragmentary.
