Dune buggy riders in the Glamis Dunes of Imperial County have known for years about a small wrecked light aircraft covered in yellow fabric. A flurry of recent site visitations and postings on social media may have caused the BLM to remove the wreckage in the first week of 2018. The mystery aircraft is a Maule M-4 Rocket built in the 1960’s. The pilot at the time of the M-4 crash was supposedly Marty “Madcap” McMaster. The M-4 was reported stolen in August 1992, but the month, day, and year of the accident is not known at this time. The N number and manufacturers serial number are not known at this time, and any additional information would be appreciated in an effort to solve this Glamis Dunes crash site mystery.
