TEXARKANA, Ark. (AP) Former NBA star David Robinson's flight to Ohio made an emergency landing Tuesday at Texarkana Regional Airport after the pilot reported smoke in the cockpit.

Robinson, his manager and a flight crew of three were not injured, airport manager Steve Luebbert said. Robinson was on his way to Cincinnati for a speaking engagement.

``They were at 40,000 feet when they called the landing in,'' said Texarkana Police Department spokesman Bart Veal. ``Apparently somebody smelled something burning, and shortly after that they did see smoke in the cockpit and called an emergency landing.''

Luebbert said the almost brand-new twin-engine Gulfstream IV is owned by Toyota. He said within 15 minutes of landing, airport workers found a floor panel that apparently was singed by overheated wiring underneath. The cause was unclear.

``The flight was going well until we started smelling some smoke,'' Robinson said. ``Hopefully, it's not anything too serious.''

On Monday night, the Spurs honored Robinson by retiring his No. 50 after a game against Utah.
