UPDATE -- NTSB board members say last November's fatal train crash in Midland could have been prevented if organizers had a safety plan.
Four veterans were killed, including Hereford native Sgt. Joshua Michael.
They say the parade's route was changed from one that didn't cross Union Pacific's tracks to a route that did cross the tracks.
Parade organizers were supposed to alert the railroad of their plans and station police at the highway grade crossing.
However; those precautions were not taken and organizers failed to get a city permit.
WASHINGTON, D.C. -- The NTSB will hold a hearing Tuesday in Washington, DC to determine the probable cause of the tragic Midland parade float railroad crossing accident in November of 2012.
The five-member Board will consider the draft report, proposed safety recommendations, and will determine the probable cause of the accident. The entire meeting will be webcast.
