a Lighter-than-air craft ( Blimp) operated by the Metropolitan Life Company- a welcome change from (snoopy on classic cars) billboards. I have seen it, it is a basically white envelope (don"t say hull, but it is an airship).
The MetLife Blimp Program started in 1987.
MetLife
Most blimps are advertising devices for companies such as Goodyear, MetLife, or Fujifilm. You will see them overhead at games played in open-air sports stadiums, but usually only in good weather.
MetLife was created in 1868.
MetLife's population is 66,000.
The company SafeGuard became part of the MetLife family because MetLife bought them out in February of 2008. More information about SafeGuard and MetLife can be found on MetLife's website.
MetLife Building was created in 1962.
MetLife Stadium was created in 2010.
MetLIfe is now a publicly traded company.
because the blimp is propelled by to engines one on each side of blimp
Blimp = tanga
If by a blimp you mean a dirigible then a blimp has more mass.
