Best wishes to those who were injured. Well, even allowing for 25kts wind over deck, it looks like they barely had 75kts IAS off the end !
It would be interesting to know what speeds they experienced in the initial fly away?

Wow, I bet his ass chewed one hell of a hole in that seat while waiting for the engines to respond.

For all those injured, get well soon you all do a great job, well done.

Obviously way too fast to recover, and looks barely even controlled. A failure, really. Was the crew courts martialled then? Or because it was only other ranks who were injured, that's all ok they flew off?Terrible.
Would you mind putting that in to plain English ?

Just out of curiosity, are you a qualified E-2 LSO?

Yea I edited my reply but it looks way too fast, looks all wrong. I'm way up for congratulating people for surviving but consider the workers, many of whom here were seriously injured.

I am going to guess that the answers are:

1. No, you are not a qualified E-2 LSO
2. No, you didn't bother to read the attached link with the report on the mechanical malfunction to do with the wire. In the future, it might be best to do a little reading.


Everyone of us who has ever served on an aircraft carrier, as soon as we read that the wire had parted during landing, immediately thought "Oh no, how many on the deck got taken out by the wire!"
Thankfully, none dead; sadly some injured.
The applause to the crew was to keep the bird out of the drink. No small feat. Your offensive assertion and assumption that applause for the crew indicates a lack of thought for the deck crew is a piss poor assumption.

Spaz - at around 18 secs on that `Bring her down some' video is that a rooster tail you can see on the water from the exhaust?!
Did he flare, or just get caught by a gust... that seemed like a very high approach over the fantail.

Not sure if it would have been the same outcome from the "Charles de Gaulle"
Good thing step down to the water was high...

Hangar, it astonishes me that you are willing to come on a thread and decree that the pilots messed up despite having never made a deck landing in your life.

how old are you?

Now.....let's hear some Air Force Zoomies tell us about that dreaded mid-day VFR approach and landing to a 10,000 x 150 foot Runway.
Or the dreaded and hazardous B52 7-engine approach!

'tartare asked: "Spaz - at around 18 secs on that `Bring her down some' video is that a rooster tail you can see on the water from the exhaust?! Did he flare, or just get caught by a gust... that seemed like a very high approach over the fantail."
I do not see a rooster tail at 18 seconds or at any other time. The approach appears 'high over the ramp' because IMHO the camera angle makes the approach seem 'high'. The LSO would not let that chap do anything crazy during the approach and if it was bad the aircraft would be waved off toot sweet - safely.

Looks like the throttle is brought to idle in error OR like the TA-4J 'throttle gets caught in the detent' (which is weird and requires a lot of imagination). Anyway the throttle does get to 'full power' soon enough to enable the aircraft to fly away. The A-4 undercarriage drops a lot in flight; so the aircraft cannot get too close to the water for ground / water effect to have much of an impact; but I can only guess. My only flared A4G landings were LPAs Low Precautionary Approaches at 160 KIAS with energy to flare - air force style above more usual Opt AoA no flare landings at between say 110-120 for example.


As for 'flaring off the front end' to stay out of the water I do not believe that has happened although we cannot see the attitude too well from camera vantage point then. The best performance is gained at optimum angle of attack so I would guess, having been well trained, that the pilot is at Opt AoA as the engine accelerates; or is at full power near the water to climb away at best. Pulling the nose higher is counterproductive in a delta wing aircraft unless JATO on.


This slow motion A4G arrest aboard HMAS Melbourne has the camera at a similar position I think - watch the 'hook runner' in motion.

There should not have been any lag/spool up time for engine response because:
1. The pilot should have had the throttles to full power as soon as he hit the deck, so when the cable parted and the Hawkeye went over the end of the deck the engines should already have been at full power.
2. The Hawkeye is fitted with T-56 engines, similar but more powerful than the C-130's and P-3's T-56 engines. The T-56 is a single spool engine with a constant RPM prop. In the air they are always at 100% RPM so there is no spool up time. They respond essentially instantly to an increase in throttle.

"...Did he flare, or just get caught by a gust... that seemed like a very high approach over the fantail."
Because that was 'tartare' last sentence I thought it referred to 'off the deck & climb away after the bolter'. However rereading it seems the sentence refers to 'at the ramp' coming over the deck/wires.


There is a trick of the light - either the white water from ship propellors or paint at round down causes the under reflection to change dramatically, giving the impression that the AoA has changed equally (the under A-4 paint is white) - but I do not think so. Sure the aircraft does something weird 'over the wires' to cause a bolter, probably too much power, which was then reduced to idle, (or raised nose but no one flares in naval aviation) and then some time to accelerate the engine when no arrest (when pilot was perhaps thinking aircraft would arrest?). All is well that ends well however unless that pilot has a good reason to explain, or was a total beginner, then he would be 'beached' probably.


Hook Runners & A4Gs MELBOURNE then 'under aircraft light change' at the ramp,

Had a wire failure on landing as it was on a Gannet setting and I was in a Scimitar. Just managed to steer onto main deck. Full power and I would be lost as I was slowed up initially. Green endorsement for my effort. All I did was save myself.

Well done 4G - Harrier pilot or just a co-incidental C/S - anyway good for you.

Arfur,

I think '4 greens' has been a standard call for naval aviators for a long time - it means ' three wheels and the hook down'.

Or you're cracking a joke - my bad if I misunderstood

Best regards as ever to all those doing carrier landings in whatever aircraft
