## Main Question or Discussion Point

If I have a contraption with wings that weighs 120 kg, the wings in total are 2 meter squared, and I make it go 60 km/h, will it fly? According to the lift equation (L = (1/2) d v^2 a CL), it should, since

L=(1/2)*1.225*277.788*2*3.39 = 1176.789

Weight = 120 kg = 1176.789 N

L = lift = 1176.789 N

D = density = 1.225 kg/m^3

V = velocity = 16.667 m/s

V^2 = velocity squared = 277.788 m/s

A = area of wings = 2 m^2

CL = coefficient of lift = 3.39

If my calculations are correct, it should fly, right? Or am I forgetting something? I'm not really sure.
