I found an ad in an '02 Hoofbeats for Space Shuttle's first season standing at Morrisville for $2000 and touting his 1:47.4 in the 2000 U.S. Pacing Champ. (Ron Pierce) beating Western Ideal, Red Bow Tie, Royalflush Hanover and Big Tom.
Goalie Jeff-Orchid Blue Chip-OTRA ... p,4, 1:47.4 ($728,695) ... five-time winner under 1:50
The endorsement from Walter - "The best 2-year-old I ever sat behind".

That made him only the second horse - behind Jenna's BB's 1:47.3 - with a race win time under 1:48 on a mile track. Ultimate Falcon's 1:47.4 win time in 1998 was at Colonial, of course not a mile track.
The next three on the (as of Dec. 2001) speed list at 1:48 were Color Me Best, P B Bullville (3yo), and Western Ideal.

Two of my favorites from the M1 and Garden State golden days were Bad Bert and Tune Town - always tried, always tough.
