Some time ago, I had the opportunity to scout the defunct Grumman airplane factory in Bethpage, Long Island. Once the leading manufacturer of everything from F-14’s to the Apollo Lunar Module, Grumman was bought by a larger company in the 1990’s and moved out of Bethpage. The enormous complex is now being converted into residential and commercial space, with many of the remaining warehouses having been converted into studio space like the one pictured below:

While scouting there recently, I got to see a few of the remaining aircraft factory warehouses. Though they’re completely empty, it was still pretty amazing. Each warehouse is enormous, stretching on for room after room after room.

The below picture gives you a sense of how much space was used for airplane assembly:

Also, when I took my tour, a few of the buildings didn’t have power…

…which was creepy, especially when you realized that some of the floors have sudden significant drops, and a wrong step could send you plummeting:

I can’t remember exactly what this was designed for – I want to say it was for working on the underside of planes, but I feel like the explanation was more clever than that. Anyone know? I seem to recall that these were capable of filling with water.

But what really interested me were the floors, which looked like brick, but were actually made of wooden blocks. Why wood? Because when you drop a 5 ton engine on wooden blocks, they don’t smash into a million pieces.

But here’s the neat thing: As I was taking pictures, I began to notice long lines of uprooted wooden blocks, zigzagging across the floor as if an earthquake had struck:

Turns out, this is a result of the wood expanding due to temperature:

It was pretty amazing how it erupted in linear patterns, stretching on for hundreds of feet across the warehouse floor. I’m curious if it was a gradual uprooting, or a sudden event:

More upturned blocks:

One last tidbit: Grumman was also responsible for designing and building the LLV, or Long Life Vehicle, which you might recognize below:

    My Polish grandmother put the armor plate behind each seat with a Polish prayer.

      We were friends with a Marine fighter pilot, now deceased, who flew F-4 Wildcats in WW2. He flew off of Fighter One on Guadalcanal, a dirt parallel runway to Henderson Field. A Jap hit his armored seat back with a 20mm round, putting shrapnel in the cockpit and cutting his face, but the armor saved (obviously) his life. If your grandmother is still alive, tell her she saved Col. (then Lt.) Sam Richards’ life in November 1942. Thank you for the great post and thank your grandmother!
      My brother in law’s Mom also worked at Grumman during the war and built the F-4’s. Her name was Rose Walbroehl. I wonder if your grandmother knew her?
      Van out.

    Worked for Grumman about 5-1/2 years. Late 80’s to early 90’s.
    The wood block floor pictures do show the affect of the wood absorbing moisture and expanding causing uplifting. Especially when the wood blocks are line up or arranged in tile form as they were. Each block’s expansion applied sideward pressure causing a weaker part of the total floor to uplift.
    I still remember the long production lines of E-2C Hawkeyes,A-6’s,
    and F-14’s on the plant floors both in Bethpage and Calverton. Especially noting the Guppy landing in Bethpage to pick up a spare space shuttle wing. Much, much history for which I am proud to be part of for the few years I had. Learned alot and good people. Its one of the few companies for which I still have pride for today in 2013. Wish very much things could have continued.

    Back in the early 90’s I was fortunate enough to live on Long Island for a couple of years. I would explore and photograph abandoned buildings in my spare time. One day I was in the Fairchild-Republic factory in Farmingdale and the floor was buckled just as you noted.

    I was puzzled by it and couldn’t find anyone to explain it. Thanks for the posting! My question is answered 20 years later.

    I remember hanging out on South Broadway (107) as a teen in the 1980’s. There were a few occasions, always late at night, that large trucks would roll into Grumman surrounded by a contingent of security vehicles that looked more like army trucks than any typical police. The trucks carried massive objects, with tarps covering them well. Traffic if any, was forced to stop and wait at the side of the road while the convoys would enter the Grumman gates. I caught a tiny glimpse of their payload once. Looked like a large ring. I would imagine a fuselage section, perhaps, or maybe a ring from a rocket section. Always well guarded. Always secret.

    My aunt, Grace Scanlon, worked and died at Grumman. She was a 26-year old plane captain and flight observer on the Avenger when a plane being tested on the runway tilted forward and the propellor snapped off. It hit Grace in the back of the head – nearly decapitated her. A newspaper article mentioned that she had endured tremendous danger in the air while helping to test the planes, only to die on the ground. It was 5 Jan 1944. She had chalked on the last Avenger off the line, Mission completed”.on 31 Dec 1943. The words stayed through the final cleaning process and the plane went on to fly many missions. When it was finally shot down, it went so gently the pilot and crew made it to the water and survived.

    Wood block industrial flooring is made from end grain wood because it is hard wearing and cut and abrasion resistant. This is the same reason that True butcher blocks are end grain on the surface not long grain. Alot of the really old wood block flooring is oak.

    Wood block floors were used because they allowed great flexibility in production line layout. If you needed to add or remove or replace a machine, it was easy. Watch some America Goes to War movies on Youtube and you’ll see guys laying the floor at amazing speed.
