Mo in town: Breeders' Cup Juvenile winner Uncle Mo arrived back at the scene of his greatest triumph in one piece - but not without some drama. The colt left New York on a Tex Sutton charter flight that was scheduled to land in Louisville at about 9 a.m. However, a warning light came on on the plane shortly into the trip. The pilot made an unscheduled stop at Dulles Airport near Washington, D.C., where the aircraft was examined and the light was found to be a false alarm. The plane departed from Dulles and landed in Louisville at 11:10 a.m.; Uncle Mo was at Churchill Downs by noon. Also on the flight was Todd Pletcher's Gulfstream Oaks winner R Heat Lightning, the likely favorite for the Kentucky Oaks.

Macho too: Risen Star winner Mucho Macho Man's van trip from Florida went so smoothly that the colt was in Louisville several hours before schedule. His van pulled into the stable area at Churchill Downs at 2:30 a.m.

More arrivals: Sunland Park Derby winner Twice The Appeal will board a plane in California tomorrow morning bound for Kentucky. The plane will stop in Arkansas to pick up Louisiana and Arkansas Derby runner-up Nehro and Arkansas Derby also-rans Sway Away and Brethren - the latter two unlikely to make the Derby field. Also boarding the plane will be Southwest runner-up JP's Gusto, although it appears that colt will pass on the Derby. After the plane lands in Louisville, he'll continue on to Lexington to catch a van for New York.

Last attempt: El Camino Real Derby winner Silver Medallion worked a half in :51.40 at Churchill Downs on Monday morning. Trainer Steve Asmussen said he'll run the colt, currently 24th on the graded earnings list, in the Lexington on Saturday at Keeneland in a last attempt to earn his way into the Derby field. With the graded earnings cutoff hovering around $240,000 this year, the winner's purse of the Lexington wouldn't bump anyone but Silver Medallion or Jaycito into the Derby field.

Not in the stars: Asmussen also said Monday that Iroquois winner Astrology, runner-up in the Sunland Park Derby, will pass on the Kentucky Derby off just one start this year. The colt will run in the Jerome at Aqueduct on Saturday.

From across the pond: UAE Derby runner-up Master of Hounds will make the trip from Ballydole in Ireland to start in the Kentucky Derby. According to Churchill Downs officials, the colt is scheduled to arrive May 3. This will be the second trip across the pond for the son of Kingmambo, who ran unplaced in the Breeders' Cup Juvenile Turf. Aidan O'Brien trains the colt for Coolmore; a rider hasn't yet been named.

Animal house: Spiral winner Animal Kingdom will breeze under Robby Albarado at Churchill Downs on Saturday morning. Trainer Graham Motion says the drill over dirt will determine if the colt starts in the Kentucky Derby.

Bubble watch: The defections of Astrology and JP's Gusto move Santiva, the beaten favorite in the Blue Grass, and Tampa Bay Derby winner Watch Me Go back into the main body of the field. However, Watch Me Go is on the fence pending his upcoming works. Should Animal Kingdom, Watch Me Go, or any others come out of the field, the next horses to get in, in order, would be Shackleford, Twinspired, Silver Medallion, Blue Laser, Flashpoint, Mr. Commons and Sway Away.
