An airplane flying across the States made an emergency landing after flight attendatns smelled something burning...An investigation was carried out, but no damage to the plane was found. Instead, it was reported that coffee may have led to the emergency landing. Inspectors concluded that the odor was probably from burnt coffee grounds in a coffee pot.
Does "may head lead" refer to "past perfect" or "past" in terms of tense? To be distinguished from "was reported", does it have to be "might have led"?
"May have led" versus "might have led" is pretty much six of one, half dozen of the other.
