Inline cockpit unable to stand re-entry heat

[Rizendell]

I've been fooling around with 1.1 and trying to make a SSTO.   Unfortunately my progress has been blocked due to an issue with the mk1 in-line cockpit.   Even with radiators attached and running, upon reentry at about 45 km up the cockpit pops.   I've tried all sorts of different variations, adding radiators and turning them on..., adding things to the front to buffer the heat, etc.   The strange thing is, its the only part that heats up and shows the meter.   none of the other parts connected seem to take any heat.  I've gotten the attached radiators up to 40% cooling before the cockpit explodes.  Its not like I'm dropping really low and fast... I've switched to the rest of the craft after the cockpit explodes and it rides out the rest of the re-entry no problemo.    Please get better QA.

Which inline cockpit? MK1 or MK2?

Is this with a design that worked in 1.0.5? Is it specific to the inline cockpit? Do other cockpits have it? Do they not have it in 1.0.5? Are you using a specific re-entry profile?

Your reentry is neither steep enough, nor are you bleeding of enough speed in the higher atmosphere. Try going down much steeper (from 80x80 km use ~150 to 160 m/s for reentry) and pancake your reentry.
