The question should be "isn't that crown a little too close to the runway?"

It's not you. I received a tape on this aircraft yesterday from within 
our flight safety community for air shows. He came extremely close to 
catching a wingtip on both the takeoff and a later pass; both times to 
the left.
In our opinion, this was a VERY close call and totally unnecessary. 
Things are bad enough in the demonstration and display community this 
year without a pilot like this one making it worse.
It's being investigated.

It's just you. The plane flies parallel and with sufficient distance to 
the crowd, so even if he'd hit the ground, nobody would have been in 
danger. The folks you see on the ground are not spectators but airshow 
stuff or pilots.
Whether the pilot put himself in danger is another question. I can't and 
won't judge it, but even if he were, that's what airshow pilots do 
routinely.
And concerning Dudley's "our flight safety community for air shows", I'm

Yes, and heaven knows that it is acceptable to put pilots and their parked 
aircraft at an unnecessary risk.

No. Their goal is to entertain the crowd but NOT put themselves in danger.

While there is no unified set of rules for airshows, there are governing 
bodies in all developed countries.  Those governing bodies usually react 
with disapproval on stupid pilot tricks (at airshows or otherwise) which put 
the public at risk.

It most certainly isn't him as I said.
The issues involved with air show flight safety involve much more than 
crowd safety. It involves ANY incident or occurrence involved with 
display and demonstration flying and that venue's peripheral issues.
In this case, this incident is of "concern" if nothing else, to the 
entire demonstration community.
There exists within the air show community a HUGE mailing list comprised 
of both current and ex- display pilots who devote copious amounts of 
their time discussing ways to make the venue safer for everyone concerned.
You may see the result of this "inside communication" going on within 
the community by obtaining a copy of Gen Des Barker's book "Zero Error 
Margin"; a complete and in-depth study of air show accidents over the 
past 3 decades with input in this volume from hundreds of display pilots 
military and civilian, past and present, including myself.
I will be most happy to supply you with information to obtain this book 
by back channel contact if you wish. I believe it is still available 
after the first printing.
Since the display communities reach is international, the event in 
Portugal is nothing unusual for us to be discussing; same for the 
Hurricane accident this week in the UK. Both are now under review, and 
recommendations no doubt will be made through proper channels that 
addresses the pertinent issues in the hope that the flight safety 
picture will be enhanced for the future.
It is partially through the input of the air show community's 
representatives that changes are suggested to and implemented by the 
various governing agencies throughout the world who control the 
demonstration safety issues.
It's a tough business and there are many of us out here who have 
dedicated our lives to helping in any way possible the betterment of 
flight safety on the air show demonstration circuit.
This year has been especially hard and many lives have been lost.
It is in part the observation, and involvement of the world's display 
pilots, in constant communication with each other, who are trying to 
make it a safer environment for all involved.

I believe that watching the videos alone isn't givng a clear picture
here.  The airfield in question I suspect has geographical aspects
that provide the spectators a different perception of risk than that
which is actually present.  Ie, the other side of the runway is lower
than the rest of the airfield.  The aircraft parked on the flightline
also contribute a bit to the illusion I think.
The pass was certainly low and close to the crowd, but I don't think
it was too much lower than I've seen here in New Zealand from similar
heavies (727 and 757 from the RNZAF mainly).

The spectators are usually laypersons and can't judge the risks, so it's 
the organisator's and the pilot's responibility to protect them. 
Contributing airshow pilots however can judge the risks (I would hope!), 
and if they decide to deliberately stand there during a flyby, it's 
their choice.

You can read, can't you? Where did I say it was their goal to endanger 
themselves? It's their goal to entertain (and probably also a bit to 
show off, I dare to assume), and to reach that goal, they accept to take 
risks.
BTW, they take routinely much bigger risks than that low flying 
airliner. Flying inverted a couple of feet above the runway is *much* 
more risky, yet done routinely at airshows and I've yet to see a post 
about that here. Probably the most stupid thing done at airshows is the 
"inverted ribbon cut", but you see it everywhere and nobody seems to 
care. E.g. http://youtube.com/watch?v=sCbwRzgJLhk. In that particular 
video you also see one low level pull in which the pilot nearly stalls 
the plane. Most dangerous at that altitude, but people don't even 
realize the situation. The same goes for those stupid low level flicks 
shortly after take off. E.g. http://youtube.com/watch?v=Uy0KkqFf_bU 
Extremely risky, because in a flick you have *never* 100% control. Yet 
nobody seems to care. But an airliner flying low... wow, *this* is going 
to cause discussions! It reminds me somewhat of the quality of certain 
newspaper reports which have been discussed here on a regular basis.
BTW, I don't say that I like such displays. Actually I hate them, and I 
don't attend airshows for that very reason. I do attend aerobatic 
competitions, though, because they are flown at a safe altitude. 
Besides, the flying there is mostly better (i.e. more precise), albeit 
less spectacular.

The problem wasn't the low pass as much as the left bank without enough 
pitch input to compensate for the lift loss.

The public WAS put at risk. Those spectators, some of whom may be pilots? 
At risk. Anyone within a couple of miles of the airport?  At risk. Clip a 
wingtip and that multi-hundred thousand pound bundle of aluminum, steel, 
titanium, and jet fuel could end up virtually anywhere within a few miles of 
the airport.

What happens to parts of the aircraft if it clips a wing tip, and starts 
spinning?  It is certainly probable, and possibly even probable that some 
parts of the aircraft could be flung in the direction of the crowd, if it 
was spinning into the ground.

It generally will not, precisely because of that momentum thing.  Instead, it
will continue flying with a damaged wing tip and some perturbation of the
flight path and handling characteristics.

Just from hitting a wing tip against something?  Do you really think the
insignificant force from clipping a wing tip can swing 200 tons of aircraft
through 90 degrees and a 200-foot radius towards a crowd?  The laws of physics
don't allow that.

In this particular film clip involving the Air Bus, had this aircraft 
caught his left tip while initiating a left bank at the airspeed he was 
maintaining through the pass, the best guess I'm getting from those I 
know who have seen the clip is an immediate nose down moment resulting 
in ground impact of the aircraft.
In short, it had all the potential of being a real mess.
After viewing the clip myself, I totally agree with this assessment. It 
was an EXTREMELY dangerous moment!
Naturally, there is no way to be absolutely certain of any reaction of 
the aircraft, but my money says it was a very bad moment.

A few years back, they were landing on 18 at OSH, and had everyone doing big 
180 degree turns from downwind, to final.  It was quite windy, and gusty, 
and there was a pretty sizeable crosswind component.
The EAA B-17 came in, and right near the last part of his turn, he was a 
little lower than he wanted to be.  A particularly big series of gust came 
up, and he ended up with his wingtip VERY near the ground.
The end result nearly had me soiling my pants.  I thought for an instant 
that I was going to witness a very bad event.  As I recall, he actually hit 
a runway (or taxiway) light with his wing tip.  You can believe that was an 
anxious moment for the pilot, and for everyone watching it.
I'm glad the outcome was just a dinged up wing, and no more.  It could have 
been very bad, indeed.

Catching a tip can go many different ways with the physics. Sometimes 
all you get is a scrape, but even then the angle would have to be fairly 
flat and the ground flat as well; but most of the time when a sudden 
ground contact catches a tip, especially in a turn, the low wing is 
descending into the contact rather than glancing flat into it and the 
result in that case can be VERY bad!

I was taking off on 27 with a direct head wind. The temp was well
above 90 and I had all 4 seats full as well as the tanks. OTOH we were
still under gross for the temp. We had just about reached rotation
when the wind abruptly changed 90 degrees to the left. so it was out
of the south. It was actually blowing us sideways  with full aileron
and max rudder. With full aileron and rudder I could no longer
accelerate and we were slowly moving to the right.  The wind was well
in excess of the Deb's capability so it was either try to   haul it
off and accelerate in ground effect or slow down while letting it
weathervane into the wind which would most likely have taken out the
gear and I had no desire to be sliding toward a tip tank full of gas
while it was being ground up. I hauled it off into ground effect and
the nose slewed a good 45 degrees to the left leaving us going down
the runway sideways.  The heads popping up in the north 40 made it
look like a prairie dog town..  Flying with your wheels only a few
inches off the pavement while going sideways is one of those *intense*
moments that seems to last almost forever. Your margin for error is
almost non existent.

A few years back I was less than 100 yards from the Corsair that hit
the bearcat on the runway at Oshkosh.. Although the F4U is a big
piston fighter from the WWII era it is tiny compared to  this monster.
At 100 yards from the F4U most of us were turning away due to the
heat.  Imagine what it'd be like from a few 100,000 gallons of jet A..
BTW when that wing tip hit it dug in.  
I also had a very good view of the one wheel landing made by Old Crow
on 36 with a cross wind no less.  The pilot did an outstanding job of
holding it on that one wheel until it could no longer stay up.  Even
then she fought the cross wind until the wing tip finally left the
pavement.  As soon as it touched the sod it grabbed and made that P-51
flip around like a "Frisbee", but at least it was flat and stopped
backwards against the build up for one of the cross taxiways.  To me
that appeared to be one outstanding job of flying the plane until it
was parked.
