63. Commander OLIVER LOCKERLAMPSONasked the Under-Secretary of State for Air whether self-sealing petrol tanks, which proved of value in 1919, are being improved, in view of the development in Germany along similar lines?
§ Sir P. SASSOONSince 1919, many types of tank for which self-sealing or non-bursting qualities have been claimed have been submitted to the Air Ministry for test, but so far none has shown sufficient merits in this direction to outweigh the accompanying disadvantages of in creased weight and diminished capacity. Other designs are still under test or are expected shorthly.
