Re: lack of stealth ?!
He was mates with Hannah Reich and had to interrogate her when the allies got their paws on her, he from his own account was not impressed with how she'd changed - he was most impressed with the 262 however. The he 177 grief (very apt name) not so much, controls were too light (still at least his didn't catch fire).
As to the carrier landings he held the world record at something like 2500 in the most different aircraft, the Navy tried to have one of their men compete - the guy got to 1400 or so, and then ended up going doolally from the stress of it. I have no doubt Brown would have tried a carrier landing in a B36 if he knew he could get away with it, but he never ever took unnecessary risks, that's why he survived.
I think I recall him saying of the 163B that it was dangerous in two ways, one the hypergolic fuels (that were explosive on their own as vapour "whatever you do... Don't bounce (Cos you wont have time to blink)" and because the aircraft out performed the pilots brain. I think from memory he's the only pilot to forget to drop the dolly, do a circuit and land, and not either be blown to smithereens or spend the next 6 months having his spine rearranged.
I'm not sure whether this is right but depending on the radar set I would imagine the propeller of the aircraft would make for a large contact, depending on the scan rate of the radar compared to the rpm of the prop what the radar might see is a huge contiguous metal plate that's about as stealthy as Farage's agenda.. A 45 degree angled panel front fairing in front of a ducted fan prop might solve that problem partially... Oh and an electric starter would be a good idea.
