Scott Lowe
of Chino, California, send me this picture when he "...found
some pictures of what I believe is one of the bases, not sure which, though
(pictures not marked)..." Is this Woodbridge or Bentwaters?
Anybody know for sure? I think
we do, now (2002). Mike
Carroll says:
"80 AHSL means Aerodrome Height
(a) Sea Level. I think it means that the picture is of Bentwaters tower
during an Air Show, maybe around the time I was there (1959-60). (written in 1998) "
Vic
Flintham adds:
"On the control tower the acronym
is AMSL which reads Above Mean Sea Level - in other words the airfield's
altitude which is written large so that aircrew may set their altimeters
before take-off. 80 AMSL fits with Bentwaters,
while Woodbridge is 70ft AMSL (written 1998)
Leo
Geis adds a new perspective:
I've been reviewing the photos thought
to be of Woodbridge or Bentwaters...the mystery tower is not likely Bentwaters.
Although the field elevation is close to that of BTW, it is also close
to that of WDB, and likely neither since even in the 1940's MSL calculations
were (my supposition) accurate to a couple of feet. Bentwaters
at 86 MSL (witnessed by my 1970's image below)
wouldn't have been estimated at 80... of course, I could be quite wrong.
However, the window configuration on the east side (front) of the tower
and the scale of the first and second story (especially the second story
catwalk) strongly suggests that this is not the BTW facility. (written
Feb 1999)

Vic
Flintham continues:
Inclined to agree with Leo and not really
happy with either option. I have checked with Paul Francis' book
on Military Airfield Architecture and have attached three scans
from it to make my point.
The first (CT1) is a standard wartime
(WW2) temporary watch office and is clearly the basis for the tower
in the second scan (CT2) which is Woodbridge.
CT3 (further down
the page) shows Bentwaters in 1994 and although much developed it
appears not to conform to the first and second types. My refs give
Bentwaters at 80' and Woodbridge at 70' however. (written March 1999)

And this from Robert
Auschermann, which has 80 AMSL and, judging by the sign, is definitely Bentwaters!
So, compare that angled pole out the back of the main structure.
Conclusive? Robert Auschermann: B/W

"We were moved to Woodbridge when they tore down the old Control
Tower at Bentwaters and then moved back when it was finished. (see Robert's page).

I think Scott Lowe's picture is of BENTWATERS. Maybe...
Unfortunately, Scott's email is no longer
valid, so I can't write back to him.
Update, December 2007
This number seems to conflict with the discussion about the photo above, with 80 AMSL on the control tower on, where people were saying that RAF Woodbridge and RAF Bentwaters twin bases had different elevation.
However, after further research today, here are two Ordnance Survey maps. Looking at a current day Ordnance Survey map, there is a brown contour line near the disused Woodbridge flightline which has -25- on it. That is 25 metres AMSL. 25 metres is 81.25 feet as near as is reasonable, so 80 might be a good round number.
Left is RAF Woodbridge (25 metres/ 81.25 feet), right is RAF Bentwaters (25 metres/ 81.25 feet) AMSL
 It looks as though "80 AMSL" could be either base! |
