Bassett is a 4 to 5 hour drive from Omaha, so if you're in southern MO, I'd guess that your drive time would be more in the 8 to 10 hour range.
I suspect that flying to Grand Island would take nearly as long as driving 'cause it can't be a high volume route. Rapid City is probably a shorter, time wise, flight and probably less expensive because RC is a bigger airport.
If it was me, I'd drive, but I'd be aware that restaurants might be closed and bring a cooler with drinks, cold cuts, bread, and condiments.
