Didn't see one specifically for these:
Sender seems to have a string of bad luck with these envelopes. Either something bulky inside, or just flimsy airmail paper. Maybe issue with high-speed sorting equipment alignment??
Seems to have happened over a period of time.
USS Yorktown (CV-10)
(Covers show from Nov 13, 1956, to Apr 3, 1957)
On 13 November, she embarked upon a round-trip to Pearl Harbor, from which she returned to Alameda on 11 December. Yorktown resumed normal operations out of Alameda upon her return and remained so employed until March 1957. On 9 March, she departed Alameda for yet another tour of duty in the Far East. She made stops at Oahu and Guam along the way and arrived at Yokosuka on 19 April.
Variety of these kinds of covers is probably endless. Show some you are particularly fond of.
