Biggest plane to do the loop?

just sat here and the thought popped into my head
whats the biggest plane to perform the loop?
I'm sure someone must've attempted it with a 747?
No one would dare deliberately try a loop in an aircraft that large or as flimsy (from an aerobatic point of view).whats the biggest plane to perform the loop?

A Korean Airlines (who else) 747 once executed an unauhorised half roll and loop followed by a dive which was recovered by the crew but which caused the aircraft extreme structural damage.
The V bombers (particularly the Vulcan) were very strong stucturally and routinely practiced half loops as part of their bombing technique.

Immelman turns where used for the lob bombing I believe? just over half a loop & then rolling level as they dived to the starting altitude. It served to massively extend the flight range of the bomb & get the bomber away from the target area as soon & as fast as possible.mattdaniels said:
a) technically it's not a 707b) technically it's not a barrell roll
Otherwise, it is a good example of what CAN be done with a larger aircraft provided the pilot knows what he's doing.
I would also emphasise that this took place over 50 years ago and modern airliners are not as over engineered as the 367-80 would have been.

One thing that nobody mentioned- Concorde could do barrel rolls; they actually did it.
During the test program the French test pilot (I think Turcat) was sitting next to the British one (Walpole) and he rolled it; and then invited the British pilot to 'unroll it' again, so he did.
They didn't ever do it with passengers onboard though; strangely they thought it might make them nervous.

Almost as good - Roly Falk rolls the prototype Vulcan at the 1955 Farnborough Airshow

My dad used to be chief pilot for Air Bristol (i.e. BAe) and he used to fly around the various BAe/Airbus plants. At one of the French sites he saw an Air France crew flying a Concorde as if it was a fighter, rolls etc were no problem by all accounts.A barrel roll is a 1g manouvre so theoretically it shouldn't place any undue stress on the airframe. Get it wrong though and..........
I can't find the pictures now but a delivery crew did some aeros in (I think) a Cessna Citation. Rippled fuselage skins, popped rivets, it was a write-off.

My old neighbour got put on a "Charge" for looping an Anson. He was serving as an operational Beaufighter pilot at the time and told me
they could pretty well unofficially get away with anything! He had to admit the loop, as tie down pickets fell forward smashing some instruments as
they fell over the top!

You'll always pull more than 1g in a barrel roll by definition - initiated from level flight you have a 1g load in the aircraft, so as soon as pitch up is applied at the start of the figure the load factor will be more than 1g. If you don't pitch up sufficiently, then you'll definately be pulling more than 1g in the recovery 
You can 'barrel' a loop in the same way that you 'barrel' a roll - by maintaining both a pitch and roll input - either intentionally or unintentionally - the distinction blurring between the two. Hence the reason the 'barrel roll' isn't a formal Aresti competition aerobatic figure, because it has no formal definition, you can't formally judge it.

"Mexican Swine Flew"The ballistic lobbing techniques employed in the early days by the V-bombers must count as the most aerobatic figures flown by large jets, and it didn't do the airframes much good as I recall.
There is plenty of footage kicking around of nutters looping AN2s - quite why you would want to, I don't know.
