Note the pancake structure of the delta wing. First use of the then revolutionary, now widespread design, in combat jets.

The wing structure is not a true delta which would be more of a triangle shape. The trailing edge of the wing structure leading back to fuselage has a more rounded aspect. More like a pancake than a true triangle.
The concept was originally intended to accommodate the employment of the twin engines. It turned out that the shape provided a number of choices in the structure and function of the plane.
Of course, just like everything in jet design (and life) there are trade offs. Eg: twin engines provides more combat reliability as well as the use of smaller, cheaper engines to get the same amount of thrust. On the other hand two engines increases the number of things that can go very seriously wrong with a very, very short response time.

It is not possible to see the apparent pancake effect in this picture. Seen from the rear the surface area between the engines is slightly curved upwards. Thus the pancake description. The advantage of of the pancake effect was increased lift, the disadvantage was increased drag.
The need for a shelf there resulted from the use of twin engines. They were placed far apart to reduce cascading damage to one engine when the other one malfunctioned. The disadvantage of that is the engines are outside of the line of flight and require even more skill than usual from the pilot because the engine arrangement dramatically exaggerated any turning effect.
American pilots loved them because they were able to receive the training and practice time necessary to stay sharp in managing the plane. American military pilots receive as much qualifying time in a month as most nations provide in a year.
Кот is a male cat, ко́шка is a female cat.
Most people use «ко́шка» as a generic term for a cat when they don't know if the cat is male or female. However, I personally tend to use «кот» when I don't know the cat's sex (probably due to influence of Belarusian, because I live in Belarus).

Thanks for pointing that out. It is the opposite of French where default cat is male. Of course, the a at the end of кошка is a clue that I missed.

There isn't much to say about words like "my" or "your" in Russian.
his/her/their do not change: его́, её, их(and they don't get an initial Н after prepositions!) my/your/our roughly follow an adjectival pattern, i.e. they copy the gender and the case of the noun they describe. Just like этот:
мой/твой/наш папамоя́/твоя́/на́шама́ма
Unlike English, no distinction is made between my and mine, her and hers etc.
Pronunciation: in «его», as well as in adjective endings and "сегодня" the letter Г is pronounced В. It is a historical spelling.
GRAMMATICAL GENDER
Nouns in Russian belong to one of three genders: feminine, masculine or neuter. If a noun means a person of a certain gender, use that one. For all other nouns look at the end of the word:
(TABLE) ENDING IN NOM; GENDER; EXAMPLES -а/-я ; feminine ; ма́ма, земля́, Росси́я, маши́на
consonant ; masculine ; сок, ма́льчик, чай, интерне́т, апельси́н
-о/-е ; neuter ; окно́, яйцо́, мо́ре
-ь ; feminine or masculine - consult a dictionary ; ло́шадь, ночь, мать, любо́вь / день, конь, медве́дь, учи́тель
IF THERE'S A SOFT SIGN, IT ISN'T POSSIBLE TO PREDICT THE GENDER, AT LEAST, NOT ACCURATELY. HOWEVER, ABOUT 65-70% OF THE MOST USED NOUNS THAT END IN -Ь ARE FEMININE. ALSO, YOU CAN LEARN THE COMMON SUFFIXES ENDING IN A SOFT SIGN THAT PRODUCE A WORD OF A PREDICTABLE GENDER. THEY ARE:
-ость/-есть, -знь → feminine -тель, -арь, -ырь → masculine
ALL NOUNS WITH -ЧЬ, ЩЬ, -ШЬ, -ЖЬ AT THE END ARE FEMININE. THE CONVENTION IS TO SPELL FEMININE NOUNS WITH A SOFT SIGN AND MASCULINE ONES WITHOUT ONE: НОЖ, ЛУЧ, МУЖ, ДУШ. IT DOESN'T AFFECT PRONUNCIATION, ANYWAY.

If you speak Portuguese... кот = gato кошка = gata
But in Portuguese, if you don't know or care, you say gato. In Russian, the opposite. The default is кошка.
Твой is the familiar singular 2nd person pronoun. You'd address a child like that, or someone you're friendly with. Ваш is the polite singular and plural 2nd person pronoun. You'd address a stranger you're not trying to piss off that way. Or your boss. Or anyone a lot older than you. Or obviously a group of people.
