2 credit cards, driving license, etc. and spending money in front
pocket... My sciatic nerves do not appreciate sitting on lumps...
I will usually have a bit more money in a bank envelope in my jacket
just in case I "need" something... Since I usually take my jacket off
in the plane it could be separated from me in a crash...
Ideas on how much walking around money is too much is relative...
Over the years I have seen guys who look like they sleep under a
bridge, pull out 10-15K in cash from their bib overalls to pay for a
tractor, or a gun. etc....
I have also seen guys who look like millionaires, Rolex, custom suit,
Mercedes, and not able to pay for a round of drinks...
It takes all kinds...

As far as him walking away - my guess is he did not (and it's a guess
only)... That engine was literally crushed from the pictures I saw -
which takes a lot of impact G force... He should have had fractured
ankles, broken wrists, in addition to lacerated liver, torn aorta,
ruptured spleen etc. from the belts, based on that picture.. Having
been a deputy coronor in my nefarious past I have pronounced a lot of
folks at their crash site... Normally, vehicle crush of that extent is
incompatible with survival... Strange things do happen though...
