Doesn't sound as if Dudley has spent much time driving an automobile
with an in-dash GPS. :-)

Nope, not much I'm afraid; but on the other hand, a bit more than a few
hours in tailwheel fighter planes if that counts for anything :-)

Being something of a tech guy, I'm a long time fan of cocpit video displays
for some purposes. I've even come around to the idea that they may be good
for some of the promary instruments--for instance there's a lot of really
informative stuff to overlay with an HSI...

However, Dudley has me convinced on this one. Swinging the nose from side
to side and watching outside is most probably the only way, unless all
traces of authenticity are abandonned and the panel is completely
modernized.

At the risk of seeming callous, this appears to be a really uncommon type of
accident and we really could take the position that "stuff happens." It is
a really scary way to meet one's demise; but everyone will be alert to the
hazard for several years, and, even if we do nothing at all, there will not
be a wave of similar accidents.

OTOH, It could be usefull to know who's on your six, andCessna 150s had rear
view mirrors as do most modern fighters. Pictures I've seen of WWII
fighters suggest that a lot of P51Ds and P38s may have had them in service
as well. The 150s had the mirror at glareshield level, while the fighters
all had/have their mirrors mounted as high as practical.

FWIW, I've seen another TBM (at Arlington / KAWO) *almost* do the same
thing (taxi into the airplane in front of him). By the time the pilot
realized why everyone was waving their arms / yelling & screaming it
was nearly too late (he locked the brakes and skidded a short distance
on the taxiway and the tail swung to one side).

If anything, this Oshkosh incident has taught me not to get in a big
line of aircraft with a large (warbird, whatever) taildragger behind
me. I'd opt for waiting like the Lancair pilot did (mentioned in the
NTSB prelim).

The truth is that I've been thinking exactly the same thing--especially
since reading the prelim--and have been advocating the same to my fellow
chapter members.

I am fairly certain that one of the greatest fears of the big warbird pilots
is the possiblity of taxiing into something, and I really doubt that any are
regecting any solution that they really think will help. Nevertheless,
accidents occasionally happen. I have a video of a Fury taxiing straight
into a parked car (fortunately unoccupied) and, if I could recall where I
got it I would post the link.

The mirror idea, whether fixed or removable, is just to provide a possible
"ace in the hole" to possibly notice a changing situation on your six.

Just FYI, the article "Taxi Smack" which is he

http://www.aviationsafetymagazine.com/sample/taxi.html

has some interesting statistics on taxi accidents. Here's a quote from that
article concerning the kind of accident that happened between the TBM
Avenger and the RV-6:

"The next most common kinds of taxi accidents, with nearly 15 percent of
the total, were collisions between two airplanes. Many involved tailwheel
airplanes in which the pilot did not have enough room to make the required
S-turns or where the pilot was looking out one side when the other side
struck another airplane.
[...]
Another common situation is an airplane approaching a crowded runup area
and either striking a waiting airplane while trying to taxi past it or not
stopping in time and striking the empennage of the waiting airplane with a
prop or wingtip."

Here's a video clip of an North American NA-50 / P-64 replica (based
on a T-6 airframe) taxiing into a parked car. Someone posted on
usenet awhile ago the particulars of what happened, and as I recall,
someone in charge at the military base (where the air show was taking
place) made the warbirds taxi down a skinny taxiway that didn't have
enough room for S-turns. The military guy in charge reportedly parked
his staff car in the way of the airplanes and the result is viewable
he

As I recall, the military (Navy?) paid for the engine tear-down /
inspection + repairs to the P-64 replica.
