I got a VIP tour of the Smithsonian’s Udvar-Hazy Center and they had his diaries laid out on a table in the preservation area, drying out from the Sri Lankan damp.
Honestly one of the coolest things I’ve ever been in a room with.
It’s the second coolest one I’ve had there. The first was shaking NASA Director Charles Bolden’s hand while standing under the shuttle he flew to space.
