Deadly crash raises questions about Marine Corps aviation

A certain level of flying hours are necessary for proficiency and the ability to react appropriately in unusual circumstances

Flying can be dangerous. I think this refueling was being done at 0200 over the ocean. You have to practice like this so you are ready if you have to do it in combat. Not sure what the cause of this latest crash is but I am sure operational tempo, the age of the aircraft, possible maintenance issues and pilot/crew error could all be in play.
