Poor airmanship or skilful 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 fuel 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, commenting 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.
