I'm sure it's a duffel bag. The brand appears to be Osprey... they do nice haversacks for hiking... never heard of them doing ejection seat covers.

Bloody hell if true - I wonder if there's a Safety Case for it - normalisation of deviance? RIP.

A retired Snowbird pilot was interviewed and he said the ejection system is not 0/0 it is 0/60 (or 60/0) .... it is old school and you need a lot more altitude than modern seats .... he also said the pilot followed procedures for power failure .... nose up , gain altitude , hit air-start .... and if no start then eject ..... and that is exactly what the pilot did ... except he ejected a bit late.

I listened to the video and there is definitely an engine "pop" just after takeoff and that is when the pilot tried to gain altitude.

(my guess) is the delay in ejecting was maybe because the pilot wanted to make sure his passenger ejected .... she was part of the team but as public relations .... she would have had some training but he wanted to make sure.

No witness reports of chutes fully opening .... pilot hit a roof and badly injured .... sadly the lady passenger hit a tree and did not survive.

Only "good" thing is the jet went straight down into a front yard so minimum residential damages

For now I'm not going to comment on how the aircraft arrived in the position it did. I do however find myself surprised by the video of the ejection. I am very familiar with MB seats and the sequencing thereof but know very little about the seats fitted to the CT 114.

The large smoke plumes and lack of an early seat separation were a surprise to me. I would have expected seats of that vintage to use sequenced charges (or even a single charge) as they moved up the rails and for an immediate drogue deployment with separation occurring as soon as tumbling stopped.

Difficult to accurately assess height and ROD but it looked like a better result should have been obtained.

So the question is, did the seats work as specified? In which case they are probably not suitable for use in the "high risk" environment of a formation display team.

Several have commented on the Snowbirds use of what is essentially a vintage jet for their displays. I am not against that providing the risks are minimised. Lets face it the alternative would probably be a Harvard 2 or disbandment. I wonder if the fitment of something like an MB Mk 8 seat has ever been considered for the Snowbirds CT 114. I know it is available as a retrofit for the T37 which also has (albeit different) a Weber seat.

Perhaps the conversation was along the lines of " we struggle to justify the costs of the Snowbirds as it is, if you insist the current seats are unsafe we will just can the team".

Whatever happens as a result of this accident I hope the Snowbirds continue. I'd love it to be in the CT 114 but I think it will cost money. Hopefully that money can be found.

Exactly.
That ejection looks very odd indeed - I've never seen smoke like that.
Possible EFATO or low thrust - use of energy to climb to height, attempted turn back and stall.
They were well into the stall before they got out; must have been right on the edge of the seat envelopes.
Pictures of those bags on top of the seats just beggars belief...

If this is indeed the actual departure then it would appear that the person who landed on the roof was in the right hand seat. Is it normal for non aircrew passengers to sit in the left hand seat of a Tutor?



unmanned_droid 18th May 2020 23:35

Indeed, the earlier photo of Captn Casey sitting in 'her' jet has her name below the cockpit on the left side too.

In the video from the guy smoking I hear a pop as the aircraft draws level with him, but I don't hear a pop from the video with the girl saying 'show off'.

Very sad event.

I had the same thoughts. Captain MacDougall had the red team helmet when he landed on the roof. Captain Casey appears to be in the left seat wearing a gray helmet in this photo.

Opinion and a bit more background on the CT-144 from You Tube user "blancolirio" who is a former USAF pilot:



RAFEngO74to09 19th May 2020 00:41

From my point of view as a former OC Armament in the days when we had RAF-manned ejection seat bays, the Weber CL-41 seat is a very old design dating back to the 1950s.

When calling it a "0/60" seat, that is before taking any downward vector into account - and there was a significant one here.

Also, the CL-41 does not have a rocket pack and the associated "dial-a-weight" function which adjusts the angle of the rocket pack to have the line of thrust through the C of G of the seat occupant.

It was not until the late-1960s when seats like the Martin Baker Mk H7 used in the Phantom started to get all the bells and whistles that most fast jet aircrew today would be familiar with.

While I appreciate him offering his expert analysis as a former tanker pilot, I'm not sure his claim at 4:00 that the Snowbirds are by far the largest jet demonstration team with the largest number of aircraft in formation is correct.

Hmmm.

Other images show that Capt Jennifer Casey had a team red helmet. Also shown are her designation and name "Public Affairs Officer * Capt Jenn....." beside the cockpit.

This image does not have a three word title and the LHS occupant has a grey helmet.

Also the background is not appear to me to be consistent with a takeoff from Kamloops 09. There should be a big river behind the aircraft (not visible) and rising ground far behind that.About a mile away from the runway.

Finally they were on a transit and they do seem to carry bags on transits.

Of course many of these can be explained away but I don't think that is the flight in question.

Here's a still from a recent video showing the gray helmet. The name on the side looks something like 'Avionics Technician Cpl Kay'. The headphones (or hearing protectors) and possibly a dark bag seem to be behind the seat.

And there's more from one seat than the other.
The Tutor is a 1960s era aircraft - does it still use the Weber seats?
Perhaps just a different type of propellant...

I thought that was unusual.

An observer saw the pilot "20 feet off the ground" and his parachute was still straight up. The nurse who worked on the passenger said her seat was beside her and the parachute was trailed but not open. Nurse interviewed on CBC an hour ago. She said she cannot believe the pilot survived.

I’m pretty sure the red you are seeing on her helmet is a visor cover.

For me it was vintage era ejection seats that led to her untimely death. I’m not sure that is forgivable. When the last option becomes the only option and it is older than you are....

None of those options seem particularly good. Perhaps the pilot was at least trying to turn towards the northwest where there's a bit of open space near the airport as well as the golf course.

There were two choices...eject or ditch in the river. The river was straight ahead and into wind. Eject raised the issue of positioning the aircraft to avoid ground damages and injuries. There was no possibility of that from a right turn after a second or so of the zoom. The other Tutor was well clear.

Had he been able to transition from the zoom to glide north to eject the aircraft would have come to earth in desert hills. Had he turned right, he could have pointed anywhere south and ejected at the top of the zoom or after stabilizing for optimal eject conditions. There is nobody on the south side of the Thompson. Nothing but desert hills.

Land on the river, unstrap and get out seems so obvious, but I suspect that is not something the military would ever consider. There was no realistic place to do a forced landing on land, certainly not that pulp mill.

Here is the overhead. The two yellow pins are where the pilot was found and where the aircraft impacted. It is 900 yards north to a safe impact area.

I wouldn't want to ditch in a jet.
The two times I've taken a ride, you're trussed up and tied in real damn tight - as you want to be.
Leg restraints, g-trousers hose and O2 feed, plus coms plug and the five point harness.
It's quite disconcerting at first.
Even with the quick release, you're not going anywhere in a hurry.
Given how quick things happen in a jet - if you needed to get out really fast - you'd be pulling the handle...!

ozbiggles 19th May 2020 05:16

Airbubba, I hate to say it and in my post I only referring to the seat....but I think it is time for those old girls. You could sway me with a 0/0 bang seat but then there is the age old problem the jet still has to go somewhere. Keep a few for museum flying under strict conditions but I actually think the news story you quote is fairly reasonable. It seems that is the plan in the next few years anyway.
I wonder too if the Pilot had part of his thought process as it was happening the risks of having a passenger have to bang out as well. Not a criticism, just another thing going on in the busiest environment you could ever have. A lot of things went wrong that day.

Yep, ejection is a last option.....right before ditching a jet!

Tutor Engine failure
zoom idle airstart
i have my checklist somewhere but it is a memory item one doesn't forget.
the pilot was new to type in January.
The pilot did not maintained control of the aircraft following an engine event and allowed a stall/spin to develop.
the seats are 0/60 in level flight and the sequence was initiated outside the envelope.
no pilot is looking down, nor are they able at the zoom attitude to say I'm avoiding a residential area

Ejection failure due to loss of aircraft control and subsequent ejection outside of the seat envelope.
a very unfortunate event that the pilot will be haunted with for the rest of his life.
RIP sister and we're here for you brother.

But there is the Thompson River directly on runway heading (either runway, it bends around the airport). However, I have no clue how well a Tutor would handle a ditching, nor whether a visiting crew would recognize that option unless they'd had a special briefing.

I understand the Tutor has a stall speed of 70 knots. Gear up it should be quite simple to ditch. McArthur Island is under 1.5 miles from the point at top of zoom and prior to the left turn. Not to land there, but close to shore, or right up against either riverbank. The river flows west there.

I suspect the military way is to try and get it somewhere safe and eject.

Ditching might be "simple" but you do need to be mindful of the point tartare made upthread about unstrapping when you mentioned ditching in your earlier post.

I can't speak take for the Weber product but I strapped into and unstrapped from various versions of M-B seats a few times in my formative years and it's not a simple task to unhook yourself completely from a ejection seat and simply climb over the side, even in the event of a rapid egress on the ground from an intact stationary aircraft.

It can also be a seriously risky process if for any reason the seat cannot be made safe and remains "live".

BTW back to tdracer's point about the quality of the "smoke"..given, as it is being claimed, these weren't rocket seats what did produce the smoke trails, Seat cartridges? Drogue gun?.

It may be a drill to do when you have speed and or height, altitude, but not at low level and relatively low speed as in just after take off. There is surely not the time at low level to get the engine back up to useful thrust and no guarantee it will start if, say the flameout or rundown, was caused by mechanical failure such as hp fuel pump drive.

Although we were taught turnbacks on the Jet Provost when I was a student in 62/63 its one reason we later stopped Low level turnbacks in the RAF many, about 40 years, ago.

I will now leave this to the investigation team to analyse.

RIP to the lady and condolences to her family and the team.

It can also be fraught with risk if the seat is live.
I think you can use the manual separation to egress rapidly in a ditching situation. The parachute will come with you, but so will the seat pack. I'm sure that was the procedure on the MB Mk4 we used on the JP where you needed the seat pack for the dingy.


Although we were taught turnbacks on the Jet Provost when I was a student in 62/63 its one reason we later stopped Low level turnbacks in the RAF many, about 40 years, ago.
When I trained on the JP in the mid 80s, students were briefed to eject after an EFATO, only the QFIs were allowed to attempt a turnback and IIRC, the parameters were 160kts and 500ft. The Mk4 seat parameters for ejecting were 0/80 and min height in the descent at 1/10th of your decent rate. So descending at 2000fpm, you needed 200ft minimum.

wiggy 19th May 2020 08:15

Hi Dan..

Yes as I recall it on the Mk 4 the separation handle was an option - still not an easy task to haul yourself out with chute and dingy attached....

We've had the JP turnback discussion before - they may have been banned for a time in the RAF, I don't know, but as you point out they were certainly taught to QFIs on the JP at CFS in the mid/late 80s..

I too heard nothing notable in the video shot from the south. The video with the audible pop was taken from the north side of the runway (left side of runway, from A/C perspective). At the nine second mark, an audible pop or crack is evident. Attached is a screenshot of the waveform. The pop occurs at 09.24 seconds, after which the recording device's automatic gain control (volume limiter) compensates for the noise (the waveform shrinks instantaneously, and gradually grows again for a half second or so). Something loud definitely occurred at around 09.24 seconds. Below the waveform image is a spectrograph of a three second portion of the audio (8.00 to 11.00 seconds). That image shows two anomalies: one, just before the 1 second mark, and another at about the 1.2-1.3 second mark (8.9 and 9.2-3 seconds according to the video timecode). Upon listening, I could detect no audible anomaly before the 9 second mark. So the spectrograph doesn't tell the whole story I'm afraid.

Whatever the speed was at the top of the manoeuvre, I think it highly likely that the angle of bank (60 deg?) selected immediately took the aircraft out of limits.

That video came out in the first hour after the crash. I think you can only hear the pop in the Cory Pelton video, the one in which the aircraft pass abeam in the air. I'd seen a bird cross during the takeoff roll and I played it back to listen for a bird strike. When you're looking for the unusual, it does stand out, and is immediately before the zoom starts. To me, it sounded like it might be a vehicle door closing. I asked Cory iif it could have been a car door and he said no. He said everybody was already out of their vehicles and waiting to watch the takeoff at the time. He saw no birds before or after. Thanks for the audio work.

Hey Bob,

Thanks, and you’re correct. I assumed (yeah, I know), amongst other things, a FJ background for team members. It seems the Snowbirds are more analogous to the Roulettes in that regard.

Unless he turned right, there was great risk of the aircraft crashing and exploding in a densely populated area. His left turn was towards a populated area, and the aircraft did crash into a front yard, but it is one theory that the left turn was to position the aircraft to come to ground north of that area in empty hills. Delaying eject to better position the aircraft for ground safety depends on maintaining a glide. And to start with sufficient height. Downtown Kamloops is straight ahead, but unlikely it would have made it there, especailly in the nose down attitude it adopted.
