There were over 60 technicians from 7 departments involved in design,engineering, fabrication, and painting. Its tail is 15 feet tall, wings are 20 feet wide and houses 6 big grills in the 38 foot long fuselage. You can cook 500 burgers an hour. It has built in gas leak detectors and fire suppression system. It's fully portable on a custom 48 foot trailer. It should be a big hit at the next company cook out.
