The magnitude of the task here....Air France 280 seconds from loss of contact to impact. MH370- 7 hours over ocean. Possible search area even if debris is confirmed, is thousands of sq nautical miles, black box acoustic pinger- 3-4000 meters. Battery ~30 days. The most inaccessible corner of the planet.
