Is the BUFF made of tin foil or something?

I remember once seeing a picture of one where the wing had snapped in half on the ground (I think between the engine pods) due to misfuelling.

Many years ago I remember a sim detail where we were given three engine failure in a B744, albeit at quite light weights, and stabilised at around 4000ft and made a successful approach and landing at Changi.

It was a combination of a maintenance error (leaving a blanking plate in a vent duct) and then failing to recognise the issue when subsequently fuelling the aircraft, with the result that air pressure building up in the tanks literally blew the wing apart. Fortunately there was no fire and nobody was injured. The maintenance crew were court-marshalled, but acquitted.

The B-52G in question flew on for a further seven years following the 1983 incident, courtesy of a replacement wing sourced from another scrapped BUFF.

Well what is the point of saying that then? , any aircraft can glide and land without any power.
Any type certified aircraft can glide to a landing. As a B-52 is not required to be type certified, it might not have this capability. Though I do not know the B-52 systems, I can imagine that it was not designed to include some of the non engine powered back up systems which certified aircraft must have. And, if all else fails, the B-52 crew can exit in flight. So it is possible that a safe gliding landing may not be possible in a B-52, as it is not in some other military aircraft.

Is the BUFF made of tin foil or something?

The B-52 is probably structurally optimized to carry flight loads, but not so over built, and heavy to carry loads which could not be encountered in flight, like misfuelling loads. Again, military aircraft may not necessarily be designed with the excess structural capacity we are used to with certified aircraft. They are saving weight and systems so they can complete their role with greater efficiency, at the expense of perhaps not withstanding uncommon or preventable events as well.

is an engine failure on takeoff almost a non-event in the B52?

"Losing an engine" now has a completely new meaning...
Sadly not.

B-52 has been around so long that the Rolls proposal to stick 4 x RB211-535E4s on them is now over 20 years old and the TF33s are still turning away...

IIRC from 40 years ago we were taught Nimrod performance to Cat A.
In the event of loss of an engine we would drift down from our maximum cruising height (depending on weight between 290 and 390) until we reached a stable level. The trick was to ensure that level was above terrain level.
Above 142,000 lb we could not maintain level flight on one engine. Once below 142,000 we could operate on 2 engines while flying below 7,000 feet. In the event of loss of one engine we could maintain a positive rate of climb of 100 ft per minute.
I imagine there would be similar drift down rules for other civil aircraft where level flight could only be achieved at a particular weight/engine state .

B-52 made of tinfoil?

It can manage things an Airbus can't....

Except they calculated the fin would have failed even earlier if it was made of tin.

Remember this one, the eng was trying to sort out the engine problems when the co looked out of the window and saw it wasn't there

As it "fell" free, bearing in mind it would still have a fair amount of fuel in its fuel system and would be burning and turning, I bet it out accelerated the B52 it was hauling along once freed from that onerous burden.
That only works if it's aerodynamicaly stable. Any pitch or yaw forces on the inlet will result in a bicycle wheel effect and a snap turn following gyro forces, the resulting drag should put it behind the aircraft petty quick.

Of course if the cause of the release was a massive engine failure YMMV

I was on a 707 training flight in 1965. Although it wasn't part of the company's procedure the instructor pilot demonstrated an approach and landing with only one inboard engine producing power. He was quick to add that it couldn't be done with only one outboard engine

I seem to remember there was a slightly B*tchy saying at the time when there was still potential for competition that the Comet buried its engines in its wing roots while 707 buried them in the countryside.......So it was said Im told

The first B727 to land at SFO was on a long approach (28L). The Captain called the Tower:
Tower we have three engines....Tower: "Braniff, hold short for United landing with engine out".

It really happened...

losing two engines

1991
Jeddah

Enroute between JED and RUH early evening with lots of turbulence around we heard a USAF aircraft, I think it was a KC135, declare an emergency.
When ATC asked the reason a very calm voice stated

" we have lost two engines"

ATC asked them to confirm - back came the cool reply:

"Yes sir, two engines have departed the airframe".

Tough aircraft.....

From Defense News:
In a separate interview at Minot Air Force Base that morning, head of Air Force Global Strike Command Gen. Robin Rand offered a similar assessment.“The engine didn’t just fall off. The engine had a failure inside the engine, and it shelled itself,” he said.
Now that we know everyone's safe, I can't help wishing there had been a camera around to catch that happening. An engine shelling itself like an extremely angry peanut ...
