A-6, F-111, Su-24, Su-34

Whilst I was already aware that the F-111 and Su-34 featured side by side seating but I had completely forgotten about the A-6 and Su-24.

I stand corrected!

Apart from a commercial aircraft that don’t really count, my first flight was in this beauty…..

According to http://duxford.iwm.org.uk/server/show/ConWebDoc.1205 there are ‘a number’ of Victors on display at the IWM Duxford in The British Aircraft Collection.

The main rotor looks like a stroboscopic effect caused by a semi synchronizing of the rotor rpm and the camera scan rate/frame rate. The main rotor is moving, you can hear the beat of the main rotor moving and causing the interferes beat effect of the shock wave from the main rotor’s shock wave and tail rotor’s shock wave crossing. (At least I think that is cause of the last effect I mention.) People that are more versed on helos can confirm or debunk my last educated guess about the shock wave beat.

1: The RPM rate of the main rotor is so well controlled/constant that it is in almost exact sync with the frame rate of the camera, causing the stroboscopic effect.

or

2: The tail rotor is genuine effect illusion, but the main rotor is digitally faked to look stopped. Both rotors are moving at normal speed.

or

3: Choppers have no lift whatsoever, they’re just so ugly that the earth repells them. (joke)

Similar phenomena, with hands on demo

This is what I first thought but in any other videos I’ve seen that happen to show this effect the rotor isn’t 100% still. In this clip however there appears to be absolutely zero rotor movement!

If I had my way, and I know this could simply not have happened, during the 70’s and 80s I would have included some Russian aircraft in the RAF.

The Beriev A40, holder of 148 world records during its service career would have complemented the Hercules and Mil Mi-24 Hind D would have been introduced instead of Pumas and a percentage of the Lynx fleet. The Hinds would have been a better choice in my opinion as they can do both load carrying and attack roles.

I would also have a small number of Il-76s in the heavy lift role again to complement the Hercs due to their 45,000kg carrying ability (compared with the Hercs 20,000kg).

I wouldn’t have bought any front line aircraft as I feel the Phantoms, Tornados (IDS not ADV), Buccaneers and Jaguars provided a formidable force compared with similer Russian aircraft.

I doubt if the F-16 is really the best CAS plane, similar the F-15.
The F-16 does the work simply because theres lots of them.
A subsonic CAS plane would be much cheaper and deliver more sorties.

A-10?

A pair of black biplanes flew out of Thruxton in formation (1610) and have been flying around doing various formation aeros over skies west of Andover.

Any idea who they could be?

Pay Rises in line with inflation but more inline with with the politicians who send our troops off to war.

Retain aircraft until a proper replacement is in place….. Canberra PR9 for example.

Expand the BBMF to cover one of every type of RAF aircraft ever flown to rename it as “RAF Memorial Flight”

For the FAA, proper Airraft Carriers returned to service ASAP

Kept the Sea Harrier

Binned the Eurofighter “Mickey Mouse” Typhoon for a proper aeroplane.

Bex

I couldn’t agree more! See,

Although it has to be said your points about the Sea Harrier, Typhoon, Aircraft carriers and Canberras are all very valid too!

I think the main thing I would change about the RAF is that I would not have started contracting out various aspects to civilian companies.

Over the years an increasing amount of RAF military activities has been contracted out to civilian companies, even the ownership of aircraft! Elementry flying training aircraft, Tutors, are owned by Vosper Thorneycroft Aviation and MELIN (Multi Engine Lead-IN) training is provided in Fireflys owned by Babcock Defence Services.

FBS cover the supply, engineering and provision of 35 Squirrel and Griffin helecopters for the Defence Helecopter Flying School at RAF Shawbury and the provision of 40% of the helecopter instructors.

The food served in the Messes is cooked by catering companies contracted in and an increasing amount of engineering works on military vehicles is being offered to contracters. This I know is rendering some REME units redundant as they watch civilians working on ‘their’ vehicles on the opposite side of the building!

This might save the government some money but is it really worth it?

Here is Upavon, still a working airfield
SE of Upavon Village, south of A342

Still used by Cadets for gliding as it was 13 years ago when I was a wee space cadet! :p

What’s this “not until 1942 in India” jazz?

And why would anyone want to remember the Defiant, Blenheim, or Gladiator?

The first line of the third paragraph here, http://www.rafmuseum.org.uk/douglas-dakota.htm
clearly states that the Dakota didn’t eneter service until 1942 in India.

Hi all

I’ve been reading the Action stations book on Cambridgeshire airfields and the section on Duxford mentions an unusual aircraft. Twin finned Wellington ‘II’ L4250 is described with a 40mm gun in a huge Dorsal turret and was at the Airfield between December ’41 & January ’42. Are there any Photos of this aircraft and what is the history of this aircraft when it left Duxford ?

There is a picture about two thirds of the way down this page;
