NEW YORK (Reuters) - Boeing Co. said on Tuesday it has requested an immediate briefing from the U.S. Air Force on the company’s failed bid for a lucrative $35 billion refueling tanker contract, which was awarded last week to a rival team of Northrop Grumman Corp. and Europe’s

Boeing said the Air Force had planned a briefing with Boeing on or after March 12, but the company said that delay was inconsistent with procurement practices.

The Chicago-based company said it was concerned with initial reports on the contract award process, which indicate that Boeing was considered the higher risk bidder.

“We do not understand how Boeing could be determined the higher risk offering,” said Mark McGraw, vice president of Boeing’s 767 tanker programs, in a statement. “It’s important for us to understand how the Air Force reached their conclusion.”
