Without statutory authority the city could not own or operate an airport. Therefore, the city has no authority other than that conferred upon it by statute and the additional authority to perform such acts as may be necessary to effectuate the authority given it by statute, although, where such authority is given, the fact that the agents of the municipality proceeded thereunder in an irregular or illegal manner will not relieve the municipality from liability.

Taking the allegations of the petition as true—the city leased portions of the passenger terminal to private corporations for the purpose of obtaining revenue, and, as a part of the consideration, turned over to each of its lessees space in the terminal for their exclusive use; and in addition, as to each of them, undertook the responsibility of maintaining certain other central portions of the building for the use of the lessees and their customers by furnishing the same, providing lights and water, and keeping them clean, neat, orderly, sanitary, and presentable. Whatever obligation the municipal authorities might otherwise have had to provide these services to the public generally, it appears that they also provided them under contract to lessees as a source of revenue, since the consideration of the leases contemplated the rendition of these services on behalf of the lessees. It was held in

The transportation industry is traditionally a function of private enterprise in this country. It has been carried on in one form or another since the birth of this nation. To begin with, the transportation of passengers was by stagecoach operated by private industry. There was later a canal system, which was done away with by the advent of the railroads and thereafter

busses on the highways. Then came the airplanes. The maintenance and operation of an airport and, incidental thereto, an airport passenger terminal, is as much a part of the transportation, business as any of its preceding enterprises. Air travel is now operating in competition with railroads, busses, and steamships. The steamship companies must keep their wharves and docks in a safe condition for their passengers. Railroads must keep their depots in a safe condition for their passengers. Bus transportation must keep its bus depots in a safe condition for its passengers. It follows, therefore, that where, as here, a city maintains an airport passenger terminal under Code § 11-201 and for a substantial profit, as a private ministerial and proprietary undertaking, and in competition with private business leases its facilities out while at the same time retaining the responsibility for maintenance of a portion of these facilities, it too, in order to escape liability, must keep the premises in its charge in a safe condition for the passengers of its lessees.

Kersey,

862 (3) (
The petition alleged: that the floor of the waiting room on which the plaintiff slipped and fell was covered with composition material in large alternating squares of contrasting colors; that it had been freshly waxed and highly polished over its entire surface; that the plaintiff slipped at a spot where a thin cake of wax of considerable area had been liberally applied and not properly distributed; that this thin cake of wax was superficially polished and transparent, so that it was invisible to a person walking toward it in an ordinarily careful and prudent manner, and had little, if any, difference in color, surface and appearance from the surrounding floor; and that it was exceedingly slick, slippery and treacherous, and constituted a menace to any person crossing the floor in an ordinarily prudent manner. These allegations are sufficient as against the defense that the plaintiff was not in the exercise of ordinary care in failing to observe and avoid the slippery portion of the floor. See
