U.S. Air Force Tech. Sgt. Daniel Caban, 1st Aircraft Maintenance Squadron crew chief, applies a portion of the Portable Magnetic Aircraft Covers to an F-22 Raptor intake at Joint Base Langley-Eustis, Virginia, Oct. 23, 2019. Caban constructed the Portable Magnetic Aircraft Covers out of Nomex IIIA fibers and specialized magnets that adhere to rigid structures without interrupting sensitive electronic components nearby and mitigates damage due to wear on the jet’s coating.
