WASHINGTON, Nov 20 (Reuters) - The pilots on a United
Airlines jet struck by an apparent weather balloon
during an October 16 flight near Moab, Utah were showered with
glass before making an emergency landing, the National
Transportation Safety Board said on Thursday.
WindBorne Systems last month said it believes one of its
balloons struck and cracked the windshield of United Flight
1093, a Boeing 737 MAX. The NTSB said the radar track of
the balloon was consistent with the United plane that was
struck.
The NTSB said "the impact resulted in both pilots being showered
with pieces of glass. The captain sustained multiple superficial
lacerations to his right arm," and the first officer was not
injured.
The NTSB said the radar track for the WindBorne
long-duration high-altitude weather balloon was consistent with
the path of the United jet. The balloon had departed Spokane,
Washington before transiting Oregon and Nevada before eventually
flying over Utah.
The captain said he noticed a distant object on the horizon
but before he could mention the object to the first officer
there was a significant impact to the windshield along with a
loud bang.
NTSB Chair Jennifer Homendy said last month "in the wrong
situation could have been really devastating for the aircraft
and those on board."
The incident raised concerns the damage could have been
caused by space debris. Prior government studies have suggested
a very small risk of debris striking jets in flight.
Airplane windshields are multi-layered to prevent a loss of
cabin pressure if damaged in flight.
The NTSB said the flight had departed Denver with 112
passengers and crew. The captain declared an emergency and
diverted safely in Salt Lake City. Passengers were transported
on another aircraft to Los Angeles later that day.
WindBorne said it has conducted more than 4,000 launches
and files notice for every balloon launched with the Federal
Aviation Administration.
