Results from a 10-1 stack of Ilford K5 emulsion flown to 38.4 km are presented. It is shown that the transverse momentum spectrum of the secondary particles of jets has two peaks at about 0.4 and 2.0 Bev/c respectively, and possibly a third peak at about 8 Bev/c; that the interaction cross section of secondary pions is considerably smaller than the geometric value; that the interactions they produce in emulsions have a lower average multiplicity than proton produced interactions in the same energy range; and that the number of particles per interaction close to the forwand direction is less than that expected from extrapolation from slightly greater angles. The results are compared with those of other experiments and their meaning discussed. (auth)
