The six-sided object was a six-sided bolt (hexagonal bullet) from a Whitworth rifle. This rifle had a hexagonal bore which required a hexagonal bullet. It was a six-sided bolt from a rebel sharpshooter that killed Union General "Uncle John" Sedgwick during the fighting at Spotsylvania Court House (American Civil War) just after he had remarked to his frightened soldiers that “They (Confederate sharpshooters) couldn’t hit an elephant at this distance”. His statement makes just about all the “famous last words” list. The sniper who is alleged to have shot him was one Sgt. Grace of the 4th Georgia Infantry.

On 9 May 1864, during the Battle of Spotsylvania, Sgt. Grace of the 4th Georgia Infantry took aim and fired at a distant Union officer. Grace was using a British Whitworth target rifle and the distance was 800 yards. Instead of a round barrel with grooves cut, the Whitworth barrel had a hexagonal twist, and a hex shaped bullet to match, for superior range and accuracy. Grace's target, Major General John Sedgwick, fell dead after uttering the words "Why, they couldn't hit an elephant at this dist...".

Sergeant Dudfoot

At the Battle of Spotsylvania, Union general John Sedgwick wqas haranguing his troops for cowardice with the words "Why, they couldn't hit an elephant at this dist..." when he was hit and killed by a bullet from a Whitworth rifle fired by Sgt. Grace of the 4th Georgia Infantry.

Whitworth rifles used a bullet with a hexagonal cross-section.

As it happens, I was in a team on the BBC quiz programme "Eggheads" recently and our failure to know the name of the general did for our chances of the £59000 prize. So it's the sort of thing that sticks in the memory!

They are a KC-10 Extender and an F-22 Raptor. The KC-10 is refuelling the F-22 mid-flight.

The characteristic tail engine of the DC-10 style aircraft was the giveaway.

A list of actors who have played film characters with a colour in the name. Many different possibilities; one set would be:
Bob Hope as The Lemon Drop Kid (eponymous)
Jennifer Rubin as Taryn White in Nightmare On Elm Street 3
Tim Roth as Mr Orange in Reservoir Dogs
Christina Ricci as Little Red Riding Hood (eponymous)
Pam Grier as Jackie Brown (eponymous)
Marvin Chatinover as Dr Gold in The Flamingo Kid
Alvin Pounder as Black Ice in Full Contact
Nick Scoggin as Gray in The Zodiac
Ralph Richardson as Sir Edward Grey in Oh What A Lovely War
Maria Aitken as Claudia Green in Asylum
[It's possible to come up with a set of all-different colours, but I decided to include both grey and gray as a sop to internationalism.]

As for an adjective, depends how you feel about him, I guess. The third, homophobic, Slim, Shady, misogynistic, exploitative, white, crap...

Balzac is the only one whose name is not printed in a color which matches the person's eye color.

Neal

Eyes

a) Liz Taylor - Her eyes are sometimes said to be violet color
b) Hannibal Lecter - Dr. Lecter is described as having maroon eyes and six fingers on one hand
c) Frank Sinatra 'Old Blue Eyes'
d) Sharbat Gula The girl with the sea green eyes
e) Honoré de Balzac WROTE "The girl with the Golden Eyes"
f) Fu Manchu "long, magnetic eyes of the true cat-green"

So Balzac is the OOO for writing about coloured eyes, rather than having them.

Venky

The colour in which the names are written refers to the colour of that person’s eyes. Elizabeth Taylor is supposed to have violet eyes. Hannibal Lecter had maroon eyes. Frank Sinatra had blue eyes and was known as Ol’ Blue Eyes. Sharbat Gula and Fu Manchu had green eyes.

Honore de Balzac wrote a book called “The Girl with the Golden Eyes” (La Fille aux Yeux D'or). He himself never had golden eyes (at least as far his portraits go). So Honore de Balzac would be the odd one out.

Owl

The question refers to eye colour:

Elizabeth Taylor: Known for her trademark violet eyes.

Hannibal Lecter: "Dr. Lecter's eyes are maroon, and they reflect the
light in pinpoints of red".

Frank Sinatra: Known by his nickname "Ol' Blue Eyes".

Sharbat Gula: The famous green-eyed Afghan Girl from the eponymous
photo by Steve McCurry.

Honoré de Balzac: Wrote the story "La Fille aux Yeux D'Or", The Girl
With the Golden Eyes.

Fu Manchu: Described in the original novels as having "long, magnetic
eyes of the true cat-green."

Honoré de Balzac is the odd one out, because the eye colour refers to
one of his works, rather than he himself.

They are voice actors for family members on "The Simpsons": Julie Kavner as Marge, Nancy Cartwright as Bart, and Yeardley Smith as Lisa.

Tommy

These three ladies are Julie Kavner, Nancy Cartwright and Yeardly Smith. They are the voices of Marge, Bart and Lisa Simpson, respectively. So, Julie is kind of Nancy and Yeardley’s mother.

The reference is to the 30-year-old BBC TV motoring programme "Top Gear", which title could also be taken to mean something you wear on your head, hence "old hat". The trinity of main presenters are: Jeremy Clarkson (the offspring of Superman, a pun on Clark [Kent]'s son), James May (the month), and Richard Hammond (the electronic organ).

Tommy

An old hat is a ‘Top’ Hat. Jeremy Clarkson, James May and Richard Hammond are the unholy trinity on Top Gear. They are the current presenters of the show that has been running in different formats for over 30 years.

Sergeant Dudfoot

Jeremy Clarkson (Clark (Kent)'s son), James May and Richard Hammond are the current presenters of Top Gear, which first aired in 1977. "Top Gear", I guess, could be considered an "old hat" way of saying "superlative".

Depicted (left to right, top to bottom) are:
- (Hero) Paul Robeson, picketing with the Civil Rights Congress at the White House, August 1948
- (Character) Capt. H.M. "Howling Mad" Murdock played by Dwight Schultz, and (actor) George Peppard playing Col. John "Hannibal" Smith, from the A-Team
- (Actor) Rupert Everett, in one of his "out" photos
- (Character) The Ringo Kid, "the name that makes killers tremble", from Marvel Comics
- (Hero) John Glenn, who first went in 1962 and went back in 1998

Actor Rupert and character Murdock form Rupert Murdoch (what's a consonant shift here or there?).
Character Ringo, heroes Paul and John, and actor George make the Fab Four Beatles.

Sergeant Dudfoot

Paul Robeson, George Peppard, the Ringo Kid and John Glenn point us towards the Beatles

Rupert Everett and (Dwight Schultz) as Howlin' Mad Murdock give us (aurally at least) the Dirty Digger.
