(CNN) -- Could a massive passenger jet slip past radar, cross international borders and land undetected? That's a key question investigators are weighing as they continue the search for Malaysia Airlines Flight 370, which vanished March 8 on a flight from Kuala Lumpur, Malaysia, bound for Beijing. Radar does have some blind spots, and it's possible to avoid being spotted by flying at low altitude, analysts told CNN. But experts are divided over whether that could be what happened to the missing Boeing 777-200ER. Jeffrey Beatty, a security consultant and former FBI special agent, says someone could have planned a route that avoided radar detection.
