That's what Big Aviation wants you to think, Newton was paid to invent Gravity in 1903 by the Wright Brothers so they could sell everyone their airplanes, and Big Aviation has been tampering with the history ever since, so we all pay for overpriced plane tickets and bland airplane food
Newton was born in 1642, and I suspect they're referring to the Great Plague of London in 1665 rather than the first and largest Black Death pandemic in the 14th century. Just in case the pedantry is important to you.
