Would you expect the tanks to explode like that? Good job he hadn't made it as far as the village beyond the airfield when he punched them off.

Certainly wouldn’t expect that... I’ve seen a few sets of full tanks jettisoned and none of them burned. I’m wondering if airfield lighting or perhaps the flash charge in a practice bomb might have provided the ignition source?

Fuel tanks - no, they don't explode when jettisoned. There were even trials against potential ignition sources where the fuel actually extinguished them.

This scenario appears to hinge on the loaded CBLS and the breakup removing the remaining safeties from the small charges in the practice bombs in an area where the fuel was atomised and (speculatively) with rather warm fuel in the tanks.

If the EJ had been earlier the fuel may not have been in such a combustible state and the CBLS may have been more intact. If the EJ had been later than the differing trajectories would have put the CBLS and tanks in different places.

Ideally a selective jettison of just the heavy stuff would be more prudent. On the mud-moving type I flew the SJ was set to clear the underwing tanks only. If the VV didn't look healthy afterwards the front seat EJ would be pressed through the panel once the throttles had hit the stops. The only further consideration was with under-fuselage fuel vs gear; plus the odd store fitted with dummy cartridges and could not be popped-off.

I’ll say it before someone else does.

In a hot location, in a Jaguar , if you lose an engine it is prudent to get rid of anything that will go.

In fact, in a Jaguar, in any location it would be wise. On most take offs.

I’m allowed to say that. The rest of you had better not get involved.

It was nice to see that the IAF complimented the pilot for saving the aircraft. Was that to have happened in the UK there would have been busloads of demonstrators, every movement broadcast by the BBC, demanding that these dangerous aircraft be scrapped and the airfield closed.

OK, it was a Jaguar but it doesn't matter.

Many years ago I saw a Jaguar lose an engine departing Coltishall. He cleaned off all the stores just as here. However, the fuel tanks just hit the ground and broke up.
After an extended circuit she came back in and landed safely.

After seeing that, I never did any spotting at either end of the runway, just to the side...…. You never know, do you?

Selective jettison (and I've done it) doesn't guarantee the stores come off simultaneously, even with a double finger stab. You then have a considerable roll input when you least need it (and I've done it).

The Clear Aircraft button was, in my opinion, the only viable option for the EFATO scenario in the Jaguar.

Well handled by the chap.

They managed to drop some practice bombs on hill 60 at Bruggen, much to the annoyance of the SWO's working party who were there filling sandbags at the time.

Quite - either jettison the stores into the overrun, or jettison the entire aircraft into the same spot.

The Summer of '76 was, as those old enough might recall, pretty damn hot.

Having finished my Hunter course, I was asked to stand in as RSO at Pembrey for a day whilst the real one was away on leave. As we drove to the range hut, I saw some very mangled 230 tanks sitting in a storage area. "What happened there?", I asked. I was told that some refresher Wg Cdr on 79 Sqn had made a monumental switch pigs, selected the wrong pylons and pickled off near on 460 gallons of HM's finest Avtur across the range. Following which, our hero asked if he could continue, but was told to RTB asap! It would only have needed the smallest spark to set the whole lot and the tinder dry range aflame!

I understand that a refresher triggernometry brief from one of 79's QWIs followed soon after the gallant Wg Cdr landed...

That was definitely a pilot who was thinking "what could possibly go wrong right now?" and not "what am I doing when I get back tonight?". Lightning quick reactions and lives to fly another day.

The F4 had enough grunt for most circumstances, but with delta fit and loaded for bear, a quick refresher that the jettison button was just ahead of the left index finger at full reheat was comforting..

Look again

I’ve just watched a slightly better quality video of the event and you will see just as he is jettisoning he appears to be approaching the wrong side of the drag curve. Quite a high sink rate with the nose still pointing up.

I’d say he wouldn’t want to have left it much longer whichever option he’d taken.

Good work.

Yes that was actually quite a close call, as you said, the better quality video shows the sink rate seen against the bottom of screen .

Notice also the grey smoke alongside the black from fuel....

I had assumed that even a mere mortal could type something into YouTube.

Try this: Jaguar Aircraft India Birdstrike
