Michelle Malkin and others note this act of treasonous sabotage on two military aircraft.

Two military helicopters were vandalized on the production line at a Boeing factory near Philadelphia, the Defense Department said Thursday as it offered a reward.

Federal officials handed out fliers to workers at the Boeing Rotorcraft Systems plant listing a $5,000 reward for information leading to whomever damaged the two H-47 Chinook helicopters.

"We have determined that this was a deliberate act and not an accident," said Ken Maupin, an agent with the Defense Criminal Investigative Service, at a news conference outside the plant.

He said 10 agents were investigating, but he would not comment on specifics or what led to the determination that it was vandalism.

The Chinook is the Army's workhorse aircraft and is used to move troops and supplies. Boeing is producing new Chinooks for the Army, as well as updating older models. The military has not grounded any helicopters now in use.

A production line at the plant has not been fully functional since Tuesday, when two workers found what the company called irregularities in the helicopters.

There are no surveillance cameras on the production line, said Jack Satterfield, a company spokesman.

U.S. Rep. Joe Sestak has said he was told that broken or severed wires were found in one helicopter and that a suspicious washer was found in a second. Maupin described the washer as being in a place it shouldn't.

"You have a large number of workers here at this point and one or more that was the problem," Maupin said. "The majority of the people here are hardworking, loyal Americans, and many of them are veterans. They want to find (those responsible) as much as we do."

U.S. Attorney Patrick Meehan said he was comfortable with the conclusion the damage was done deliberately.

These are things that could kill our men and women in uniform -- and which impair their readiness for combat by delaying the arrival no needed weapons into combat zones. I'm sure that this is one of the folks who thinks they are "supporting the troops" by interfering with their getting what they need to kill the enemy -- and I hope that the bastard(s) involved find themselves spending a great deal of time in prison when they are caught.
