| V-22 Osprey |
 |
The V-22 Osprey is a joint service,
multimission, military tiltrotor aircraft
with both a vertical takeoff and landing
(VTOL) and short takeoff and landing
capability (STOL)Built by Boeing
Helicopters-Bell textron. It is designed to
perform missions like a conventional
helicopter with the long-range, high-speed
cruise performance of a turboprop aircraft.
The initial operators are the U.S. Marine
Corps and United States Air Force. The FAA
classifies the Osprey as a model of powered
lift aircraft.The Osprey is the world's first
production tiltrotor aircraft, with one
three-bladed proprotor, turboprop engine, and
transmission nacelle mounted on each wingtip.
It typically operates as a helicopter with
the nacelles vertical (rotors horizontal) for
takeoff and landing. Once airborne, the
nacelles rotate forward 90° in as little as
12 seconds for horizontal flight, converting
the V-22 to a more fuel-efficient,
higher-speed turboprop airplane. STOL
rolling-takeoff and landing capability is
achieved by having the nacelles tilted
forward up to 45°. For compact storage and
transport, the V-22's wing rotates to align,
front-to-back, with the fuselage. The
proprotors can also fold in a sequence taking
90 seconds.The V-22's development processes
have been long and controversial. When the
development budget, first set at $2.5 billion
in 1986, had reached $30 billion in 1988,
then-Defense Secretary Dick Cheney zeroed out
the budget, but was overruled by Congress.
The first flight occurred on March 19, 1989.
Additionally, the V-22 squadron's former
commander at New River, Lieutenant Colonel
Odin Lieberman, reputedly instructed his unit
that they needed to falsify maintenance
records to make the plane appear more
reliable. A crew member's recording included
him stating that "We need to lie or
manipulate the data, or however you wanna
call it".On September 28, 2005, the Pentagon
formally approved full-rate production for
the V-22. The current plan is to boost
production from 11 a year to 24 to 48 a year
by 2012. Planned production quantities
include 360 for the Marine Corps, 48 for the
Navy, 50 for the Air Force. The U.S. Army,
originally the lead service for the
then-named JVX program, is also a candidate
for possible applications.
On December 12, 2005, the Pentagon announced
that the procurement budget for the Marine
Corps V-22s would be reduced by $1.1 billion
over the production run.
Israel has shown interest in the purchase of
an undisclosed number of MV-22s, but an order
has not been placed or approved

The V-22 Osprey is a joint service,
multi-mission military aircraft with vertical
take-off and landing (VTOL) capability. It is
designed to perform VTOL missions like a
conventional helicopter while also having the
long-range cruise abilities of a twin
turboprop aircraft. See in the first minute
or so, the helicopter takes off and than the
engines are leaned forward, so it can fly
horizontaly as a twin turboprop aircraft!
Amazing!

| Blackbird Attack Osprey |
 |
Video shows an in-flight attack of an osprey
by a red-winged blackbird. Also shows Osprey
diving after fish, feeding nestlings, tearing
food apart, swooping, calling, defending
nest, responding to intruders, protecting
nestlings, nestling, flying and other
characteristics of their lives. In one part
of the video, the osprey carries a large
chunk of fish in its talons. In other parts,
osprey can be seen diving for prey.
The osprey can fly to from Venezuela to Ohio
in 2 weeks. It can fly at 60 mph and can
cover 600 miles in one day.
The Osprey (Pandion haliaetus) is also called
the fish eagle, seahawk, or fish hawk. It is
a huge fish-eating predator. This raptor is
24 in. in length, has a 6 ft. wingspan, and
can weigh up to almost 5 lbs.
Its head is white with a dark mask across the
eyes that reaches to the sides of the neck.
The irises of its eyes are golden to brown
with a transparent bale blue nictitating
membrane. It is whitish on the head and
underparts with a brownish eyepatch and
wings.
It has a very complicated call, as shown
here-with a large vocabulary of sounds. Its
calls include sharp whistles, and a sort of
shreek. In this video, as boaters approached
the nest, the birds gave a great variety of
calls. The Osprey can arch its wings, which
gives it a gull type appearance.
Ospreys normally mate for life and live 20-25
years.
In heraldry, the Osprey is depicted as a
white eagle. It is featured on 50 postage
stamps. In mythology, a king became a sea
eagle to attack his dauthter when she fell in
love with Minos, king of Crete.
It has been variously classified with the
falcons, hawks, and eagles. It is unusual in
that it is a single species that occurs
nearly everywhere in the world and in all
climates.

| Osprey In East Providence Rhode Island |
 |
Here are some shots of Osprey who nest in
East Providence, RI. I visited this spot last
year. Last year these two were just
hatchlins,
Osprey (Pandion haliaetus), also known
colloquially as seahawk, fish hawk or fish
eagle, is a diurnal, fish-eating bird of
prey. It is a large raptor, reaching 60
centimetres (24 in) in length with a 1.8
metre (6 ft) wingspan. It is brown on the
upperparts and predominantly whitish on the
head and underparts, with a brownish eyepatch
and wings.
The Osprey tolerates a wide variety of
habitats, nesting in any location near a body
of water providing an adequate food supply.
It is found on all continents except
Antarctica although in South America it
occurs only as a non-breeding migrant.
As its other common names suggest, the
Osprey's diet consists almost exclusively of
fish. It has evolved specialised physical
characteristics and exhibits some unique
behaviours to assist in hunting and catching
prey. As a result of these unique
characteristics, it has been given its own
taxonomic genus, Pandion and family,
Pandionidae. Four subspecies are usually
recognised. Despite its propensity to nest
near water, the Osprey is not a sea-eagle.
