A 10-foot rocket bearing four experiments made a five-minute flight Thursday in what was called the first truly private, commercial space flight.

The rocket, dwarfed by larger space rockets launched here, burned its motor for only 4.4 seconds as it pushed the payload container to an altitude of about 14,000 feet, or less than three miles.The payload was later recovered from the Atlantic Ocean even though the main parachute on the rocket failed to open.

E'Prime Aerospace Co. of Titusville hopes the rocket, LOFT-1, will attract investors.

LOFT-1 carried a thin-film polymer experiment from Morton Thiokol Inc. and Utah State University, and a flight monitoring system for measuring acceleration and temperature from QSI Corp. and Weber State College in Utah.
