Arlington Sisu

Al Parker spent 10-1/2 hours in this cockpit when he flew the Museum's Sisu sailplane non-stop 647 miles (1,042 km) from Odessa, TX, to Kimball, NE, on July 31, 1964. He scanned these instruments, the sky, and the land, for signs of lift – a flick of the variometer needle, billowing cumulus clouds, or a patch of dark earth bathed in sunlight that might spawn vigorous thermals.
