If we recreated the scene from fast & furious 7 and dropped a challenger srt® hellcat redeye widebody from a c-130 aircraft at 5,280 ft, how much horsepower would it take to drive past it before it hits the ground if you're 1 mile away? pro tips air density @ sea level, 59 degrees, no wind = p = .002377 slugs/ft^3 coefficient of drag (flat plate, nasa) = c(d) = 1.28 weight = w = 4451 lbs gravitation constant = g = 32.2 ft/sec^2 area = a = 197.5" long x 78.2" wide x (1 ft^2/ 144 in^2) vehicle falls flat, wheels 1st, straight down, at constant acceleration with no aerodynamic drag until terminal velocity horsepower needed to accelerate is average - not peak 100% driveline efficiency
