MH370 Search: How Currents Could Have Carried Debris

Scientifically speaking, there's no reason the airplane fragment found Wednesday on Reunion island in the Indian Ocean, couldn't be from Malaysia Airlines Flight 370 — even though it's 4,000 miles away from MH370's last known position before it vanished.
Investigators said it's too early to tell for sure whether the fragment really is from Flight 370, which disappeared with 239 people aboard in March 2014.
