Any idea on the cause of the emergency?

Where was this VC-10 heading for?

What aircraft was it, Brize Norton Based?

Rob!

Lots of emergency's yesterday at YYT.
An AeroMexico 762 was there due to a medical emergency and later, I saw an Aer Lingus A330 land for reasons unknown.
They usually come in threes!

Perhaps 'emergency' is a bit dramatic. 'Unscheduled' is a more realistic description.

It is not uncommon for the hose to fail to retract. They simply land the aircraft and wind the hose in by hand.


It does beg the question though, if it had been an aircraft with a boom that did not come up, how much damage would that cause?

Saint,

When a boom fails to stow it usually means the AF is about to spend around 1.5 mil for a new one (KC-10). The boom just hangs down and contacts the ground sort of like an arrestor hook with sparks flying everywhere, but the damage to the boom is always substantial

If a centerline or wing drogue fails to retract and they land with it, the hose must be changed out (no reeling in by hand) since it's contacted the runway and most likely has structural integrity issues now.

Does it happen often on the -10?

I should've elaborated a bit more on my last post. Sorry. The emergency I was referring to is the "LANDING WITH DROGUE/BOOM IN TRAIL". That one isn't very common at all. I can only think of 3 or 4 times I've heard it's happened in the 25 years the KC-10 has been flying. On the 135 it's more common, but definitely isn't an everyday thing. Guesstimating once every 2 or 3 years.

There are a couple other checklists related to this sort of thing, but the one I've ran the most (twice) is "BOOM LATCH FAILURE". That's where it's stowed flush where it should be, but the boom latch won't lock into place. With that it's just hydraulic tension on the cable keeping the boom in the stowed position, no lock. That ones pretty easy, you just gotta be sure to have mx install a boom support sling before you shut down #3 after parking, or otherwise depressurize the #3 hydraulic system

Duce,

I'm not suggesting that a hose would not be damaged, but if you are away from home you would hand wind it in until you got back to base. The only time I have seen one myself resulted in some minor chafing to the basket. Memory fails me as to whether the hose was replaced but it does seem likely.

Interesting about the boom though. If it doesn't retract can you cut the hydraulics so that it'll be pushed up by the impact with the ground or does it just have to wear away / break?

Gotcha. I don't know if USAF crews would just reel the basket in. My guess is they'd just take the thing off and just strap it on a pallet. Maybe have an MRT come out for the problem which caused the drogue to stay trailed if there was no hydro specialist on the flight already. Long answer yes with an "if", short answer no with a "but".

I'm not sure what you mean by cutting the hydraulics, but your last part was right. When you land with the boom in trail it's not as if the boom is rigid and won't move around at all. It'll go wherever the slipstream (and ground) make it go. Don't think it will break off, all I've heard is the boom just scrapes on the ground like you'd expect.

If anyone knows where I can post a 22 MB video file of a KC-10 landing in Alaska (Elemendorf) with the boom in trail I'll post the thing. Still waiting for the Fairchild B-52 to be digitized though

Yesterday, I've seen a Bundeswehr A310 tanker doing a go around with both drogues trailing behind (my bedroom window, which is right over my desk with my PC, faces the western end of runway 07/25).
