Well, sadly, if the time between the pull up and the stall, and the push
back down and hit the runway only took about 45 seconds, there was not
much time to say anything.

Russian crash investigators find voice recorder
The last word the pilot of the Boeing 737 uttered was "circle." Moments
later the jetliner slammed into the ground, investigators said Wednesday,
killing all 50 people on board.
The Moscow-based Interstate Aviation Committee, which investigates plane
crashes across the former Soviet Union, concluded a day earlier that the
crew failed to land at first attempt, began to stall in a steep climb, then
overcompensated -- plunging the plane into a near-vertical dive. The report
was based on the data retrieved from the plane's flight parameters
recorder, which also showed that its engines and other systems were working
fine until the plane hit the ground.
On Wednesday, search teams found a tape of cockpit conversations -- a
crucial piece of evidence that was missing when its container was found the
day before. The recording is expected to shed light upon the motives behind
the series of faulty maneuvers that led to the crash.
Vladimir Markin, a spokesman for the Investigative Committee, Russia's
main criminal investigative agency conducting its own probe into the crash,
said that recordings of the crew's conversations with the control tower
sounded routine.
The pilot reported that the plane was in a wrong position for the landing
and confirmed getting a traffic controller's command to circle the airport
prior to making a second run. "The final word the pilot said before the
crash was 'circle,'" Markin said in a statement.
The Tatarstan Airlines plane was flying from Moscow to the central city
of Kazan, 720 kilometers (450 miles) to the east.
Moscow's Interstate Aviation Committee's report concluded that to prepare
the jet for a second try, the crew switched off autopilot and put the
plane's engines on maximum power, raising the plane's nose to an angle of
about 25 degrees. The abrupt move apparently caused the jetliner to lose
speed.
The normal procedure during an aborted landing is to apply near-maximum
power and assume about a 5-to-7 degree nose-up attitude, said Kevin Hiatt,
a former Delta Air Lines chief pilot and president of the Flight Safety
Foundation, a U.S.-based nonprofit.
"Twenty-five degrees nose-up is excessive. There's no question about that
whatsoever," Hiatt said. "Why they determined they needed to go to that
high an angle will be part of the investigation."
At an altitude of about 700 meters (2,200 feet), the crew then tried to
gain speed in order to avert a stall by putting the nose of the plane down.
The report said the plane then went into a dive of about 75 degrees and hit
the tarmac.
Airplanes can sometimes recover from steep dives but they must be at a
sufficiently high altitude.
The committee said it took only 45 seconds from the moment the crew put
the engines at maximum throttle until the moment the Boeing smashed into
the ground.
Such "loss of control" accidents are responsible for more deaths than any
other type of plane crash because they are rarely survivable, according to
the Flight Safety Foundation, an industry-supported global aviation safety
nonprofit based in Alexandria, Virginia.
The head of Tartarstan Airlines, Aksan Giniyatullin, said Tuesday that
the plane's two pilots had sufficient experience, ranging from 1,900 to
2,500 hours, but admitted that they apparently had no experience with
attempting a second landing.
