Sea Vixen down

Why jettison the canopy? Not equipped with a bang seat, or the canopy not fitted with detonation cord?
There is certainly a bang seat, possibly it was to make it easier to get out in a hurry without ejecting. Though judging from a video I saw the canopy was jettisoned when the Vixen was already sliding down the runway, not sure why that was.According the instruction book (below) you aren't supposed to jettison the canopy in a belly landing.

Though 'back in the day' they'd jettison the canopy before impact in case it didn't open afterwards.
I was at Duxford just over a month ago, stood near a family whose grandpa had a flight in a two-seat Spitfire. After it had landed and taxied back it took almost 15 minutes before his canopy could be persuaded to slide back.Dr Jekyll said:

Canopy operation is electric, and apparently in service the canopy manual un-lock was not the most reliable of devices, so likely the decision was made to power eject canopy at point of touch down, as pilot was likely turning all electric power off at touch-down as a safety measure.https://www.seavixen.org/images/documents/Pt4._2._...

Hydraulic systems all 4!

Was it a selector issue?
Interesting documents. A few years ago I had the opportunity to chat with the chief tech on the Sea Vixen, he explained to us how the flight controls and hydraulic systems in XP924 are very different to how the aircraft was operated in service as XP924 was modified by Flight Refuelling to D.3 status, so XP924 has fully powered controls to suit radio control.Have a read..

Maybe retaining the canopy meant it was less likely to sink if it slid off the end of a carrier, and wasn't applicable to landing ashore ?I fear the worst with this. I happen to have a copy of the Sea Vixen A.P. at work, the damage to the bottom of those frames is really nasty. The frame webs (pink bits on the images) are made of titanium sheet and the A.P. pretty much states that these parts should be replaced rather than any attempt to repair made. Which would mean stripping and rebuilding the entire rear fuselage.

As per my post when it happened.While, technically, its possible to repair her........it will be a hugely time consuming (and likely eye wateringly expensive) undertaking and I suspect that understandably, the decision will be taken not to do so.
Bloody brilliant bit of flying though by Hargs to set her down as gently as he did.
