It would be easy to think that Heydrich was killed outright by the bomb blast, but that is not correct.

The attempt on his life was made at a point where the road took a hair-pin turn so the car had to slow to about 10 mph. There was also a bus stop located very close by, so a fellow standing there with a package would not look out of place.

As the car slowed the bomb thrower pitched it into Heydrich's lap, but the driver speeded up and the bomb landed in the back seat where it then went off.

Now have you ever had a Mercedes seat apart and seen all that crumbling horsehair they have in them? Well, in those days they used real horsehair, and when the bomb when off Heydrich's body was filled up with bits of springs and leather and horsehair. He lived for several days, but died of infections from all the stuff that was floating around in him.

Hitler threw him a big state funeral and then ordered Mercedes to build armored cars for what were known as 'the big heads'. Mercedes did not have a chassis that could take the weight, so they bought up a bunch of SSK's from the 30's, stripped them down and built new bodies.

The one that was sent to Prague was used by their fire department after the war and is now on display there.

And..... Heydrich insisted on riding in an open car since he thought it would show the Czechs just how brave he was and/or how inferior Czechs were to Germans.

Not one of his better decisions.
