"15.7 WING−SWEEP EMERGENCIES
15.7.1 Aft Wing−Sweep Landings

CV arrestments are permitted with up to 40° of wing sweep, and emergency barricade engagements are permitted with up to 35° of wing sweep. Shipboard aft wing−sweep landings should be conducted at 15 units AOA. Field aft wing−sweep landings may be conducted at AOAs up to 17 units when wings are stuck aft of 50° to minimize approach airspeed for normal landings or remain within published field arresting gear limitations for short−field arrested landings. Main flaps and slats should be utilized to reduce approach speed with aft wing sweeps up to 50°. Maneuver flaps may be utilized if main flaps and slats fail to extend. If wings are determined to be stuck aft of 20° position:

1. Emergency WING SWEEP handle Match Captain Bars With Actual Wing−Sweep Position Tape.

15.7.2 Asymmetric Wing Sweep
Refer to Chapter 11 for asymmetric wing−sweep design limitations and flight characteristics.
With asymmetric wing−sweep emergency condition, divert field landing is preferable to a CV landing attempt. Aircrew must fully consider approach speed and aircraft controllability characteristics prior to attempting CV arrestment. See Figure 15−2 for recommended approach airspeed for 14 or 15 units AOA with asymmetric wing configurations."

I think since they were a flight of two that his wing man was the lead ship and therefore had transponder on and the accident aircraft transponder was in standby.

The obvious question is what happened that he had to get out so quick, though my understanding is the services that operate fast jets (in the US at least) frown upon people saving aircraft when “by the book” they were supposed to eject.

I expect this one was lost, too. I mean, why else would you go there?

WARNING
Humour:
Yes I am aware the aircraft is 100 million $. I guess the cartoon didn’t take cost overruns into account.
In any case somebody has a new “Callsign”.
Also: For all the press asking “How could they lose an airplane???!!!!” ……”You are aware the damned thing is a ‘Stealth Aircraft’ are you not? Seems we got that working pretty good!”

Humour Over

Based on the art, I'm guessing that's a "Far Side" cartoon - in which case it's at least 28 years old (the Gary Larson retired in 1995) - so $40 million would be about right...

So if there was 'weather' could this event have started with a lightning strike?

Hank Caruso cartoon!

Well, it certainly ended with a Lightning strike.

Has there been any clarification elsewhere on this curious quote from DaDrive article above:
"..."He's unsure of where his plane crashed," the dispatcher can be heard saying at one point. "Said he just lost it in the weather." It's unclear whether or not this means that weather was a factor in the incident or that the pilot had simply lost sight of the aircraft as it flew on due to clouds or other ambient conditions...."

Circulating on Twitter... suggestions it's fake - wrong time of day, weather and terrain...

Did you look at the dates on any/all of these? Yes, they are published daily but they are not recent work.

To return to the advertised program - have any pictures of the crash site or debris field been published?

If I may wordsmith this a bit: a {Phantom, Hornet, Lightning II} suffered strike damage is something I've seen in official reports.
In any case, well played megan. :D

If you were the USMC, would you publish any if you didn't have to?
I wouldn't, were I the regional commander. (And when the usual FOIA request came in, one would doubtless comply per usual ...)

I believe that the f-35B has Auto Eject. Perhaps the computer said "Go"?

gums 21st Sep 2023 17:26

Salute!

The Bee has an auto eject feature when in the last of the landing modes.

Apparently the USMC and maybe the RN Harrier folks wanted this. Seems the plane could roll rather sharply if certain things failed, and the installed system was quicker than the pilot.

Guess we wait for a report from USMC, and it might be a long time.......

And BTW, even the primitive FBW jet I flew 40 years ago would fly at last commanded/trimmed roll rate and gee following ejection unless completely outta control. So early motor failure crashes and controlled ejections were typified by descriptions of the jet flying ahead until reaching the AoA limiter, then descending until impact. One even landed slightly ahead of the pilot, broke one gear but was in fairly good shape. And the Thunderbird a coupla years back has a good pic of the plane that "landed" short of the rwy at Pete Field. Didn't burn and had only a few hundred pounds of gas left. Was throttle linkage failure and engine shut down when he retarded the throttle - "power lever angle" in some manuals, heh heh.

Gums sends...
