PREVIOUSLY REPORTED TO NUFORC: 1/13/2004 3:25:05 AM 03:25. Investigated by Iowa MUFON,Beverly Trout and Pam Brackenbury. Described as "rounded" triangle, (hovering when first seen) on west side of I-35 southbound lanes,near the Truro, Iowa Exit, with no flashing lights, no sound, and close enough that witnesses were viewing the underside of the object, estimated at 50-300 feet in altitutde. (Altitude was estimated based on a nearby radio tower. [NOTE: There were 3 white triangular-shaped lights (and this is the second case we've investigated recently where lights on a triangle are described as triangular in shape instead of circular)with the longer leg of each triangular light following the "outline" of the side of the object (where the light is positioned) rather than being positioned at the apices.] One circular red light is reported between two of the triangular white lights. Witnesses stopped the car as soon as they had passed the object, got out seemingly for perhaps 10 seconds, and were astounded when they got back in the car to discover the car clock now read 10:57 p.m. [NOTE: This is a time scenario which seems to contradict the 10:13 p.m.time-stamped sales ticket from a Walmart store just before they left to drive the 26 miles to the Truro exit...i.e. it should have taken no more than (at most) 25 minutes to reach the Truro exit, and there is a 44 minute time-span to consider] When the 2 witnesses got out of their car, in a few seconds the hovering object sped away to the north and "almost instanteously" approached an airliner on approach to the Des Moines Airport, then turned and headed away. Only one of the 2 witnesses was interviewed, the other witness was out of town and has not contacted investigators to set up an interview - and this is often the case where one witness is willing to talk, but a second witness may be somewhat hesitant.((NUFORC Note: We express our gratitude to Beverly Trout and Pam Brackenbury, of MUFON/IOWA, for following up on the case, and for their follow-up report.
