Yup - Wash from the wings. Seen and had it done to me several times from low flyers. Work site was an air combat range - lotsa fun watching the crazies.
C-5 generates a HUGE wall.
Depending on whether you are referring to the intense exhaust (jet blast) on the ground or the swirling atmospheric disruption (wake turbulence) in the air, a jet’s displaced air can last for up to 3 minutes and travel over 10 miles.
Airliners landing one after another are often warned about wake turbulence from other planes up to 10 miles in front of them.
