Poor airmanship or skillful pilot?
Most probably both.
The new video (actually posted to Youtube a couple of years ago - thanks to Juanma Baiutti for the heads-up), that will likely add fuel to the debate about the alleged braveness of this kind of stunts, shows an F/A-18 Hornet of the Spanish Air Force performing a low-level flyby along a taxiway at Gando airbase, on the Canary Islands.
As already explained several times on this blog, concerning the famous Argentine pilots' flybys, such “improvised air shows” can be very dangerous, even when they don’t imply difficult maneuvers. Indeed, the problem is that, in Aviation, “improvised” things are usually “dangerous” things.
