that time where you crash.
Firepilot is absolutely correct, the youtube video is showing a foolish stunt where the amazing part is the Pampa pilot is lucky to be alive (even
luckier if he kept his flight rating and avoided a court martial.)
300 knots indicated, 1 meter AGL over a grass airdrome ( perpendicular to the tarmac and dead straight towards unsheltered spectators as well:@@

pretty well showcases the pilot in the vid as being both inexperienced and overconfident.
A couple points of interest worth noting... the atmosphere is not homogenous, the atmosphere is dynamic and in constant flux which is turbulence. For
example, The temperature difference between grass and asphalt can easily span 20 degrees fahrenheit. As air temperature increases air rises however,
as the temperature rises, air density and potential lift decrease. As it takes a 300knot aircraft a bit less than 1/150th second to travel that single
meter between sky and terra firma, I'm sure most reading can guess why these type of situation are best avoided by the career orientated pilot.
Lastly, the 1/2 Km of open grass potentially had lots of potential surprise ready for our young Fuerza Aerea Argentina friend (Any idea what happens
when aircraft aluminum and plexiglas merge into pigeonburger at 500 fps)? If the hypothetical bird strike or ground squirrel wasn't enough, I was
particularly impressed with all of the loose clothing and knickknacks sent flying as the spectators dove for life and limb. I would have been really
impressed watching the pilot pull off a restart with a meter of alt after sucking some poor guys toupee through the compressor.
Surprisingly, most aviation professionals would also agree that was an amazing maneuver
Amazingly poor judgment.

What's the saying about old pilots and bold pilots?
Looking at the stubby chord aerofoil design and high wing placement, I doubt the IA 63 Pampa sees any noticeable ground effect benefits when slow and
dirty much less at 300KIAS where the airfoil is somewhere near VA (optimal maneuvering speed) and has nothing more to gain from the reduction in
induced drag ground effect might afford.
Hope this helps....
