That's RW26 at Bournemouth, Al. Does get a bit 'Brown Pants' there sometimes. Iv'e even been in Haskins Garden centre at Ferndown when something big goes out, and thought 'Sh1t...that's coming in here' ;D ;D ;D ;D ;D

I met a flight there earlier this month, a Tui 737/800, which used pretty much all of the runway length to slow down, although I don't think he was trying very hard ::)

I'm not sure that I am brave/daft enough to stand where that camera was with an EAC jumbo heading towards me though... :o

Looking at the weather conditions in the area at the time and what is known (in the public arena), my money is going on a simple cloud burst followed by structural failure  :(

These are very common at this time of year in that part of the world and can quite easily drag any aircraft up at a good 5 or 6G. This followed by a nasty microburst downdraft could rip the aircraft to pieces if it wasn't in tip top condition and lets be honest here, the A320-200 has been around for donkeys years and aircraft maintenance in some parts of the world is scheduled by accountants not engineers  :(

Lizzie, unless the USAF has started sailing aircraft carriers, you will probably find that that F14 was in fact a F15C from Bitburg in sausage land  ;D

Guffer, "quote .... When properly prepared it could go vertical and then supersonic.....although the prep for such a stunt would degrade the exoskeleton airframe which thus limited it's service life and was it's eventual demise"

What makes you think that ??
I'm asking because I spent 3 1/2 years of my life taking them off the squadron, stripping them down to the shell, fixing anything that needed doing / upgrading then rebuilding / testing the aircraft and sending it back out to the flight line so the piggin jockeys can break / bend them again  ;)

LC0112G  The Streak Eagle was a stripped down, tuned up one off airframe and had very little in common with the USAF's F15's.  Also, no way on earth could it do mach 1.4 @ sea level  ;) In fact the F15 is shite at anything above mach at low level due to the wing loading. That's why it was common practice during exercises for the lightning pilots to lead them down low if they wanted to have a fight  ;)
That time to height record was set up in response to the soviets Mig 25 (go faster version) in the good old cold war tradition of  my dick aeroplane is better then yours  ;D
The time to height record also used a stepped climb profile to get there which is very similar to how the lightning got up there so fast.
Standing on your tail over the threshold is for air shows / the public only unless the boss isn't looking   :D

Nah, that's not a take off...

That's a take off... 8)

Bet he'd chewed through his pants by the time he was airborne.

Anyway, this is a takeoff.

I love Youtube comments.. "OMG how can you not see this is FAKE!"  ::) ;D

Precisely what you said :y

The requirement to constantly fix/replace parts of the exoframe was not cost effective and if I recall correctly there was only a limited number of times it could be polished (and thus reach maximum speed) before the entire airframe was written off.

It was a fantastic aircraft though, and I am tempted to hop over to SA where they still have one flying ::)

TG, you say that about the age of the A320... this one was only 8 years old :-\

Quote
The aircraft was an Airbus A320-216, with serial number 3648, registered as PK-AXC. It first flew on 25 September 2008, and was delivered to AirAsia on 15 October 2008. The plane had accumulated approximately 23,000 flight hours over 13,600 flights. It had undergone its most recent scheduled maintenance on 16 November 2014. [21] The aircraft was powered by two CFM International CFM56-5B6 engines and was configured to carry 180 passengers.

Ok, not the newest, but nearly twenty years newer than some A320s I could name :y

Looking forward to my trip on an Airbus A321 on Saturday, now!

The F-15 is my Mastermind specialised subject :) Agree with most of that, except....

The structural design limits on an F-15 are Mach 1.4 at sea level. This was achieved during the flight test program.
http://www.alternatewars.com/SAC/F-15C_Eagle_SAC_-_February_1992.pdf

However, this is in a clean configuration, and it was extremely rare for any Bitburg, Spang or Soesterburg Eagle to fly in clean configuration. Even at airshows they usually had centreline and wing pylons fitted. The release to service limit is 800KIAS. However, the wing loading does make for a bumpy ride at low level, and few crews I've spoken to have exceeded M1.4 even at altitude.

The lower level time to climb records (up to 15K meters) were done in a single climb . Those involved accelerating to M1.4 as "sea level" then pulling 4g and climbing at 50 degrees nose high. The records above 15K meters were done in 2 steps - M1.1 at "sea level", Immelman up to around 35K feet, accelerate to M2.2 then 50 degrees up till the engines flame out. 

The records were set at Grand Forks AFB in North Dakota, which is 913ft AMSL, so not "sea level" I'll concede that. The temperature was also very sub zero, so nice dense air for the engines to breath.

Anyway - looking more likely now that this plane somehow got into a flat or spiral spin that the crew couldn't recover before structural failure.

Watching the glider clip, that is impressive for an aircraft with no engine 8)

But it lead me to a couple of very impressive videos, one a take off and one not...

Last first...

What an achievement

Sounds like Mr Wood is providing some of the commentary on that :y

And the first last, saw a vid titled "B737 takes off from Lasham... just" which wasn't that impressive, but did lead me to this one...

A nice short field take off

Thread drift .... but if you really want short field landings and takeoffs ..

and then there is JATO assist ..

I remember my first winch launch in a glider.  Nobody warned me what it would be like  :o :o :o ;D

Well, technically, it's got an LPG'd Chevy 502, it just leaves it on the ground. ;D

It does take a couple of them before you're able to stay sufficiently together to fly the plane.  ;D

On my first one was in a Schleicher Ka-2 and the cable broke at 800 feet. In "lowering the nose" the instructor managed to deposit all the dirt that was hanging around on the floor of that old hunk of wood and fabric straight onto my bonce!

Like this Lizzie  :y

Take Off


Thanks Emd, but no.  The one I saw went straight up from flying at just a few feet above the runway, completely vertical, like a rocker and without any rolls into a clear blue yonder! 8) 8) :y
