stumbled upon this picture on the net and realized that I have
noticed similar vortices when I fly commercial airlines. Being the
commerce student that I am, I was wondering whether the trailing
whites were because of change in the altitude or temperature.
Reading up on these was very interesting and also scientifically
answers why a flock of birds fly in V
Also scared to fly in the flimsy ATR
(propellar) aircrafts from now on. It seems the wingtip vortices
from large aircrafts may destabilize smaller aircrafts following
them, especially while taking off and landing. The landing and take
off of ATRs are as such a thrilling experience, now they are going
to be more so.
