Coltishall. loved it 12th Oct 2021 19:24

Was lucky enough to have a back seat with the tall gentleman on 16R serca 2003. Best day of my life! Practice bombs on the range, low over Humber bridge, very low over Chatsworth house, then low over Ladybower and incredibly low through the Mach Loop. Then upstairs for some aeros. From memory I'm sure we were up just under 2 hours and returned to Colt lowish on fuel and the 4g left turn after flying down the runway just seemed to go on forever "hence the pile issues ever since"

Said gentleman went on to be very successful with the "reds" I've still got a digital pick of him next to the 16R sign and the reds taxiing behind him (they were doing the seaside shows and operating out of Colt)
Back to the thread, what speed were we going? dint have time to look at gauge as at 200 feet it all seems bloody quick.
Just wish I'd tried harder at school

Incorrect. Peacetime clearance for F3 was 725KIAS Vno and 750KIAS Vne. There were various speeds above that for operational necessity, under Operational Emergency Clearance (OEC), one of which was 850KIAS for F3. I did hear that 900KIAS was also authorised at one point and I do know some that got to that with ease before the DECUs were trimmed back following some uncontained engine issues.

We still do OECs these days and you can read about their policy here: https://assets.publishing.service.go...30_Issue_5.pdf

LJ,
Thanks for the correction - I was going from memory. The 800 KCAS was what I remember from the R to S trials and I thought that had become the NE limit - my mistake. Must dig out some old Manuals ....

As I recall his rotate speed was 193 that day and when he pulled back on the stick the jet didn’t want to rotate.

What followed was a high speed abort, a cable engagement and a few shredded tyres.

What also followed was early finishes for the remainder of the detachment.

What I should add was that on the first day of ops there we received 14 noise complaints from our use of runway 30. One of the complaints was from the Mayor.

Apparently the locals were happy with the A10s overflying the city on take off. They were not so happy with Jags in reheat at low altitude straight over downtown.

Some people just have no sense of humour.

Cheers BV. Was the Jet E fit as well? I wouldn't know as it was before my time and assume the hot and high was enough to forget it. No Jag operating on a States det is clean. Hindsight is a fine thing (and I have a memory as well). RCS seems to be an engineers nightmare! Top bloke as we all know, but the last two major 6 bird strikes at Colt, he was flying! XX737, I have just got the F700 for (and donated to the RAF Colt Heritage Centre). Its terminal birdstrike was by RCS (and he never raised the F707 entry! I had to do so!). Queen of the Fleet XX112 also became a magnet for feathers in RCS's hand just before the closure of Colt. The scatter of gulls on the Head Up as RCS popped their mortal coils was most impressive. The comments by Dava of "Why didn't you divert to Coningsby?" was very apt at the time.
I have flown in a Jag that is Cool and Clean and one that was Hot and Dirty. One was a sporty Hawk, One was not. Chalk and Chesse. Watching a runway disapear as Lift and Thrust tries to beats Drag and Mass on the second did make this HNC quailfied engineer wonder. However the Jaguar is always going to be the most social aeroplane. It allowed the aircrew and groundcrew the opportunity have a drink during dets. In fact it was the last OC of a Jaguar Sqn that ensured that the JPs recognised the ground crew outside of the management structure. Morning briefs when I was SLOC. Groundcrew Recce. Name the Ground Crew from his mug shot. Then again the last Jaguar OC was Chershire, not Gibson. The end of the Jaguar was the best of days one would ever see.

“My fastest/lowest combination was 700 KIAS at 100 ft overland in a CF-104 out of Cold Lake - and that was spectacular!”


Blimey, that must have been some ride! I managed 650+ (not sure by how much) IAS below 100ft in a jumping bean. Yes, I know that is WELL above VNE but I was in a bit of a rush to get a firing solution at the bottom of a screaming-Jesus dive from 10k with the limiters tripped. The aircraft didn’t react well to the first Lima launch and I ended up with 140 degrees of instantaneous roll to starboard and a face-full of sea.


The other guy had it worse though. Swing the lamp.

Do you reckon that was the sudden loss of drag off of the left wing station or the rocket eflux from the 9L?

Best, LJ

One thing I could never fathom and neither could some of our avionics engineers was our Sengo / Jengo’s insistence to run the NavWass etc at Deci with the Avionics bay door open “for cooling” thus destroying the effectiveness of the built in cooling system by destroying the flow through the boxes. Never could understand the logic behind that.


i do have a picture somewhere of the spotty Jag fitted with the Adour 821 engine…

I can only surmise that it was the effect of the shockwave as the Lima went supersonic as soon as it left the rails. Got my attention whatever the cause!

So many Tomb and Tonka mates that are jealous of you Mog. Only SHAR mates have thrown a Lima at the enemy as an AAM (forgetting the own goal of the 25th of May 1982). Strike Gordon released a Lima off a Jag in combat. That was using a 9L as a ASM!

Only mentioned historical facts. I will disappoint.
