The ad's headline read: "It descends from the heavens. Ironically it unleashes hell."
Executives for Boeing and Bell Helicopter called a halt to the ad campaign after it appeared in Air Force Magazine and Armed Forces Journal, the St. Louis Post-Dispatch reported. The ad ran a third time, in the National Journal, because of a clerical error.
Ibrahim Hooper, a spokesman for the Council on American-Islamic Relations, said he feared ads like the one for the Osprey could spark vandalism at mosques.
"Any time you have American troops rappelling to a house of worship, it's going to raise some red flags, and at this time of crisis to have American troops attacking a mosque that's clearly labeled as a mosque, it just sends a very negative message," Hooper said.
