Training
Platforms
Depth
6m
Details
We have three training platforms on the site that have
been constructed from 40ft x 20ft Shipping Containers.
These provide
not only provide a stable, safe and exciting training platform but
also act as a great swim-through attraction.
Before placing
them in the water we did a great deal of work on the containers;
drilling holes, cutting metal, and constructing wooden floors. As
you would expect a great deal of preparation work was undertaken
to ensure both front and back panels were completely removed and
all sharp areas taken away. We also welded on a 2ft hand rail to
each of the new training platforms that cover 3 sides of the top.
The training
platforms are more than capable of each taking up to 12 students
at a time.
All the units
have been painted white with a massive stencil informing you all
that they are training platforms, so there are no excuses for getting
lost!

British
Aerospace Jetstream 200
Depth
11m
Details
This attraction arrived on the site towards the end of
2006 and can be found at the north end of the quarry between 2 training
platforms.
Originally designed
as a light passenger and business aircraft, the Jetstream now serves
additionally as a Royal Air Force and Fleet Air Arm crew trainer.
After the prototype flew in August 1967, Jetstream development costs
forced the original manufacturer, the Handley Page company, out
of business in 1970. A succession of companies kept the design alive
immediately after this and Scottish Aviation at Prestwick took over
in 1972 with a production order for 26 multi-engined pilot training
aircraft for the RAF.

Royal Air Force (RAF) Wessex
Helicopter Mk5
Depth
17m
Details
This attraction is one of two Wessex helicopters sourced
from the Royal Navy which arrived at the National Diving & Activity
Centre on 7th November 2007.
After
a great deal or work making the attraction diver friendly; on 17th
December 2007, it was carefully lowered into the water by a 100
tonne crane with help from Police Specialist Underwater & Search
teams, along with representatives from the Army, Navy and RAF.
History
The Wessex was developed under license by Westland Aircraft, initially
for the Royal Navy, but later for the Royal Air Force (RAF). The
Wessex was built at Westland's factory at Yeovil in Somerset.
The early Wessex
helicopters were first used by the RAF in 1962, and did not finally
retire until January 2003, being the main transport helicopter until
the introduction of the Puma.
The Navy pressed
the development of the Wessex into the improved Mk3, coming into
service in 1967. A later version of the Wessex used by the Royal
Marine Commandos was the Mk5.

Alvis
Stalwart Amphibious Vehicle 'Stolly'
Depth
11m
Details
Designed
in 1959 this 6x6 wheeled truck/boat is an Amphibious armoured vehicle
with waterjet propulsion. It's role was that of general amphibious
transport truck, many units being fitted with a hydraulic crane
and raised central canvas tilt support.Unfortunately,
rapid technical advancement in helicopter design rendered its usefulness
in all-terrain load carrying prematurely obsolete. Which is why
we have one sat at the bottom of our quarry!
Over 1400 of these vehicles were produced, ending in 1971. This
vehicle was declared obsolete in 1992.
This attraction
can be found between one of our training platforms and the Alvis
Saracen Troop Carrier.
Size 6.35m x 2.62m x 3.12m

also welded onto the parts that divers potentially could squeeze
