Question about air turbulence?
How fast does air around the fuselage of a plane move compared to its
velocity. for example, if a plane is flying very close to the ground at 300mph per hour over my head, will I get blasted by 300mph gust? somebody let me know. thanks. |

No -- you might feel some wind as it goes by, due to air displacement/replacement, but nothing like 300 mph. Remember, the air is standing still, with the plane flying through it. What you will feel is the turbulence due to air friction and lift -- sort of like what you feel when a car speeds by. |

Here's my guess ..er.. I mean estimate: a downdraft of 30 MPH, which proceeds as fast as the wings. It takes downwards air to lift planes up. Brian Whatcott Altus OK |

Question about air turbulence?
So would it be safe to say that a large commercial aircraft flying overhead
at a stupidly low altitude like 20 feet wouldn't be nearly strong enough to overturn vehicles?

At the local international aiport a road goes past each end of the runway well below the flightpath. I've never heard of was tipping anything over on these roads. However there is an embankment at one end which is close to the level of the runway which when I was young was fun to stand on when the planes came in or took off overhead. The wash here was significant but fear made people fall down more then the wind. These days there are signs there warning of the dangers of jet blast and men come and yell at you if you stand there. I guess people were injured after being knocked over by the wash or falling down in fear. The wake of the body of the plane going over was inconsequential compared to the wash from the engines. I reckon it would be possible to knock over a high sided vehicle with the engine wash, but it'd need to be sideways under a large jet taking off. |

I was held for takeoff behind a good size passenger jet at Exeter (I think it was) long ago in a powered g;lider (a Fornier RF4) When cleared I hit it, and at about 50 feet did a smart involuntary 90 degree roll, and headed straight for the tower. I corrected when I could, and put it down to vortex interception. Controllers weren't so careful of it at the time Brian Whatcott Altus OK |
