MACK, CO, USA
N7011C
North American SNJ-4 (AT-6)
The pilot had landed at this airport 'at least a dozen times' in the past 15 years, and was aware of 'a low crop at the approach end of [runway] 25.' He said he had this same picture in his mind as he made his approach. When he was approximately 200 to 300 feet from the runway, he realized he was too low (the corn stalks were 8 to 10 feet tall). He applied power and up elevator, but the airplane contacted the corn stalks, settled to the ground, rolled a short distance, then nosed over.

He applied power and up elevator, but the airplane contacted the corn stalks, settled to the ground, rolled a short distance, then nosed over. Both wings and the horizontal and vertical stabilizers were extensively damaged.
