he work to transform
Brooklands Museum, covered
in depth in the March issue, is
gathering pace. Completion of
the first stage of the
£8.1-million Heritage Lottery Fund-
backed Brooklands Aircraft Factory and
Race Track Revival project was marked at
the museum’s Double Twelve Motorsport
Festival on 17-18 June when Goodwood
supremo Lord March re-opened the
track’s finishing straight. It has been

refurbished for motoring use for the first
time since 1940. Meanwhile, the Aircraft
Factory — using the restored WW2-
vintage Bellman hangar — and Flight
Shed buildings are nearly finished, with a
scheduled opening in October. The
museum is looking for donations to
complete fundraising towards both.
Over at Dunsfold Park airfield, the latest
taxi run by Brooklands Museum’s ex-RAF
VC10 K3 ZA150 took place on Saturday
15 July. Its next activity will be on Sunday
27 August, in the form of a full-bore taxi
run as part of the annual Wings and
Wheels show at Dunsfold being staged

on 26-27 August. On both the Saturday
and Sunday of that weekend, there will be
tours inside the aircraft. Various
Brooklands-organised activities will again
feature at Wings and Wheels — see
http://www.wingsandwheels.net for more
information. Ben Dunnell

BAC stressed that the layouts were
based on preliminary discussions
“with many of the world’s major
airlines”. The aircraft could be ready
for service in 1969. It claimed that the
rear-mounted engine layout “provides
a long-range turbofan aircraft of the
size needed at the end of the decade
and which has a true profit potential
greater than any other similar capacity
aircraft on offer at this time.”
But by May 1966 BAC had come
up with another double-decker. It
could have been built in two versions,
one with wing-mounted engines, the
other with aft-mounted powerplants.
In both cases power would have come
from a quartet of high-bypass ratio
turbofans.
The former version would have
been able to carry a 70,000lb
(31,800kg) payload and the latter
74,200lb (33,700kg). Direct operating
costs for the rear-engined version
were expected to be 6.5 per cent
better than the other due, it was
claimed by BAC, to lower drag and
less weight.
There were, though, some safety-
related issues raised by these ideas.
The double-deck arrangement could
have created difficulties in the event of
an emergency evacuation with lengthy
escape slides required for upper deck
passengers. Lower deck occupants
would have been uncomfortably close
to the ground in a heavy or wheels-up
landing. Ditchings on water could
have been problematic, too.

On the other hand, the deeper
fuselage would have brought added
structural strength to the VC10’s long
nose, while the altered aerodynamics
removed the need for special
nosewheel tyres to eliminate the risk
in wet weather of spray being ingested
by the engines.
BAC’s legendary chief test pilot
Brian Trubshaw was convinced there
were no insurmountable difficulties.
He told Lance Cole, author of VC10:
Icon of the Skies — BOAC, Boeing and
a Jet Age Battle (published by Pen and
Sword) that the double-decker was
“entirely viable.”

Because the basis of the idea was
for one VC10 fuselage on top of
another, much of the tooling had
already been paid for and costings
could have been kept reasonably
low. Cole told Aeroplane: “Trubshaw
was convinced that it was a viable
engineering and marketing project
which would have competed directly
with the DC-9-60 and wiped out the
Boeing 707-400. He considered it a
brilliant project which was technically
viable.”
BAC’s engineers continued to
seek other ways of increasing the
VC10’s capacity. One proposal, dated
February 1966, envisaged a 300-seat
single-decker with rear-mounted
engines and an oval, four-arc-section
fuselage with space for 10-abreast
seating.

And they were busy on VC10
developments into the 1970s. This
is confirmed by a brochure dated
December 1971, which described a
proposal to accommodate 179 to 225
passengers at 31in (79cm) pitch, with
power courtesy of a pair of rear-
mounted Rolls-Royce RB211s.
This design was designated RTOL/
VC10/RB211, the first four letters
standing for reduced take-off and
landing as it was envisaged that
in short-haul form it would offer
sparkling field performance. A long-
haul variant would have had more
conventional performance.
Interestingly, this proposal seems
to have been under consideration
at Weybridge a year after the
government had refused support
for the promising BAC Three-
Eleven and decided against official
participation in the European Airbus
programme.
By now, though, wide-body aircraft
had become a reality. The first Boeing
747 had arrived at Heathrow in
1970 and all the proposed VC10
developments stayed firmly on the
drawing board. For a while, though,
a double-deck version of the British
four-jet airliner had seemed like a
good idea.
So, as the Airbus A380 marks the
10th anniversary of its entry into
commercial service, it’s interesting to
speculate whether Britain really
could have been first with a
double-deck jet airliner.
